Version 1.0 November 2025

Sandy Bay flood map overview

To see the maps in more detail, go to www.ses.tas.gov.au/floodmaps/www.hobartcity.com.au/City-services/Stormwater-and-urban-waterways/Flood-risk-and-maps .

Tasmanians need to prepare for flood events that may not happen often as well as the minor flooding they may have experienced.

If you live, work or often visit Sandy Bay or surrounding areas, it is important you understand what a flood can look like so you can prepare. There is likely to be a flood that causes significant damage in the area at least once in your lifetime.

When there is heavy intense rain the Sandy Bay Rivulet can flood low-lying roadways and properties around

  • Lower Waterworks Road/ Lynton Avenue/ Davey Place
  • Bottom of Pillinger Street/ Digney Street/ Fitzroy Place to Regent Street
  • Sandy Bay Road near Dr Syntax / Jersey St area / Osborne St area
  • Quayle Street / Balmoral Street area
  • Marieville Esplanade and waterside areas.

Other minor waterways or overland flow can impact

  • Lower Duke Street/ Sandy Bay Road / Margaret Street area
  • Proctors Road/ UTAS Sandy Bay Campus
  • Lambert Rivulet surrounds,
  • Sandy Bay Road between Derwent Water Avenue and Ethelmont Road
  • Lower Sandy Bay / Sandown Park/ Nutgrove area
  • Sandy Bay Road to the north of Cartright Reserve
  • Parts of Hobart are prone to flash flooding, depending on how rain falls across kunanyi/ Mount Wellington. This means there can be little warning before waterways flood.
  • There can also be stormwater run-off in other places if there is heavy rain. This can be difficult to predict.
  • Areas near the waterfront are also affected by tides and coastal inundation, especially around Marieville Esplanade.

Flooding can isolate properties for a short time, depending on where the rain falls and how heavy it is. Even if your home is not flooded you should prepare for

  • isolation
  • potential power and telecommunications outages.

Waterways in the area are short, so flooding is likely to be for hours rather than days after rain stops. If you are safe at home or elsewhere, it is usually best to stay where you are until the flooding subsides. If you need to evacuate, pick up children from school or travel for some other reason, you should do so early, before flood waters rise.

The maps in this guide show the level of flooding that has a 1% chance of happening any year (Annual Exceedance Probability (AEP)) due to riverine flooding from Sandy Bay Rivulet and nearby minor waterways.

Check TasALERT.com or listen to ABC local radio Hobart 90.5FM or 936 AM for warnings and advice.

您有洪水风险吗?

Example past flooding events around Hobart include:

  • May 2018 – The Southern Tasmanian Extreme Weather Event caused flooding around Hobart. There was 236mm of rain on Kunanyi/ Mount Wellington in 24 hours. 
  • April 1960 – About 200mm of rain over 3 days and caused damage across Hobart.
  • June 1947 – Two separate flooding events impacted the Hobart area.

我应该怎么做?

  • Check the map to see whether your home or business is at risk of being flooded. If it is, you should have a plan for leaving during a flood event.
  • Check if you can safely get to or from your home, work, or school during a flood. If you need to leave during a flood, make sure your route is safe or leave early before floodwaters rise. If you need to evacuate during a flood, make sure your route safe and think about:
    • where you would go
    • how you could get there
    • what you need to take.
  • Prepare your home or business to minimise possible flood damage.
  • Prepare a Home Emergency Plan. See 做好应急准备 – A guide for individuals and households to prepare for emergencies . 
  • If you have a business in the area, you should have a plan that covers flooding.  Business Tasmania can help– see www.business.tas.gov.au/managing/risk_management .   
  • During a flood event, go to TasALERT.com or listen to ABC local radio to find out about evacuation centres or other places to shelter. 
  • TasALERT’s risk ready tool also lets you check your property’s exposure to a range of hazards. See alert.tas.gov.au/get-ready/risk-ready/

Floods like the one shown on the map, or worse, will occur again. No two floods are the same.

If you live in a low-lying area or near a watercourse, your house may flood. Even if your home is safe, you may need to detour around flooded areas or your road access may be cut.

Never drive into or enter flood waters. Roads and bridges may be washed out or unsafe. Avoid travel during floods.

了解该怎么做可以拯救你的生命并帮助保护你的财产。制定家庭应急计划是准备工作的最佳方法之一。决定天气和降雨触发条件,以便知道何时采取行动。.

Bureau of Meteorology (BoM) Forecasts, Warnings, and Observations

Whenever 大雨 is expected in an area, the Bureau issues

  • a Flood Watch
  • Severe Weather Warning and/or
  • Thunderstorm Warning for heavy rainfall that may lead to flash flooding.

The time between the warning and heavy rain falling can vary from an hour to 24 hours or more. It is best to act on the warnings from the Bureau of Meteorology rather than wait for local flooding alerts.

Tracking Rainfall on Kunanyi/ Mount Wellington can help predict flooding around Hobart. Go to www.bom.gov.au/tas/ .

Mt Koonya Radar is useful to see when and where heavy rainfall is falling.

洪水水位

While no two floods are the same, the following describes what you can expect at different flood levels around the area. Even if your property is not flooded, you need to think about access. Different levels of rainfall can cause flooding depending on its

  • intensity
  • duration
  • how wet the ground is beforehand, and
  • where the rain falls.

In minor flood events

  • Riverine flood water and storm water run-off may reach some building floor levels and impact low-lying paths, parks and backyards.

中度洪水

  • May mean water starts to enter some homes and other buildings
  • There may be water across some key routes, such as Sandy Bay Road and Churchill Avenue/ Regent Street.
  • Traffic is likely to become gridlocked in these conditions.

A major flood event

  • May be for example due to heavy rainfall in the river catchment of about
    • 17mm or more in half an hour
    • 36mm or more in 3 hours
    • 51mm or more in 6 hours (5% AEP @ Hobart)
  • Is likely to cause flooding over major thoroughfares in places, cutting access in some places. Traffic conditions are likely to be difficult.
  • May isolate many properties for short periods. Flooding should quickly dissipate once rain stops.
  • May inundate many low-lying areas. Flooding is likely to be more hazardous around:
    • Lower Waterworks Road/ Lynton Avenue/ Davey Place
    • Bottom of Pillinger Street/ Digney Street/ Fitzroy Place to Regent Street
    • Sandy Bay Road near Dr Syntax / Jersey St area / Osborne St area
    • Quayle Street / Balmoral Street area
    • Marieville Esplanade and waterside areas.
    • Lower Duke Street/ Sandy Bay Road / Margaret Street area
    • Proctors Road/ UTAS Sandy Bay Campus
    • Sandy Bay Road between Derwent Water Avenue and Ethelmont Road
    • Lower Sandy Bay / Sandown Park/ Nutgrove area
  • Sandy Bay Road to the north of Cartright Reserve
  • May include storm water run-off impacting other areas.
  • Increase landslip and coastal erosion risks.

Weather systems causing such rainfall can also often cause coastal storm surge, particularly at high tide.

Know your risk, prepare, reduce risk where you can, connect with others, keep up to date and act safe.

洪水之前

了解您的风险

塔斯马尼亚州经常发生洪水,可能造成广泛而重大的损失。在过去的 200 年里,塔斯马尼亚州有 78 人死于与洪水有关的事故。本指南旨在帮助您了解您所在地区的洪水风险。.

TasALERT’s risk ready tool lets you check your property’s exposure to a range of hazards. See alert.tas.gov.au/get-ready/risk-ready/

2. 准备您的家庭

制定涵盖风暴和洪水的应急计划

考虑一下在风暴或洪水来临时你会怎么做,这意味着你会有更好的准备,每个人都会更安全。制定一个你的家庭成员都明白的应急计划。有一些清单可以帮助你完善你的计划——请看 做好应急准备 – 个人和家庭应急准备指南。. 
定期检查您的计划,并让家中的每一位成员都模拟可能影响您家庭的洪水场景进行演练。.

准备一个应急包

准备好了

  • 电池供电的收音机和手电筒,备用电池
  • 重要信息,例如您的应急计划
  • 紧急电话号码列表
  • 食物和水
  • 急救箱
  • 橡胶或结实的皮革手套

视情况打包

  • 保暖衣物、结实的鞋子或靴子
  • 药品、眼镜或其他必需品
  • 手机和充电器
  • 宠物食品以及它们所需的其他任何物品
  • 照片和特别的纪念品
  • 重要文件,例如
    • 保险单据
    • 护照和
    • 出生证明

定期测试收音机和手电筒里的电池。.

3. 尽可能降低洪水风险

  • 在购买、维护或开发房产时,请考虑风暴、洪水和其他危险。.
  • 修剪或移除您家中、商铺上方或您物业附近电线上方的树木和树枝。.
  • 保持雨水槽和排水沟畅通。.

4. 与他人联系

认识你的邻居并参与社区活动。一个联系紧密的社区在紧急情况下更安全、更有韧性,并且有助于每个人在事后更好地恢复。检查家人和邻居是否安全,是否了解正在发生的情况。.

5. Keep up to date

留意周围发生的事情。定期查看预报、观测和警报。. 

6. Act Safe

  • 看管好孩子。.
  • 为应对可能的电力、供水或网络中断做好准备。.
  • 检查您的应急包是否已准备好。.
  • 避开积水区域,如排水沟。. 永不 在洪水期间徒步、玩耍、骑车或驾车。您无法分辨水下有什么,也无法判断水深或水流速度。在仅 20 厘米的快速流动的水中,很容易被冲走并溺水。洪水可能很危险。.

当地面发生洪水时

  • 将家用物品放在高处以最大程度地减少可能的损坏。.
  • 如果安全的话,请关闭水电煤气。. 
  • 一种防止污水倒灌回家的好方法是将沙袋放入塑料袋中,然后用它们堵住马桶、覆盖排水管和水槽。.
  • 趁还能安全离开就走。.

如果您需要撤离

  • 遵循 SES / 塔斯马尼亚警方 的建议。.  
  • 带上你的应急包。. 
  • 去安全地点或避难中心与亲友会合。. 
  • 让别人知道你去了哪里。.

照顾好您的动物

在紧急情况下,您有责任照顾好您的动物。如果您有宠物和其他动物,在洪水或其他紧急情况下疏散需要更长的时间。在洪水可能上涨之前,将牲畜转移到易受洪水影响的地区。欲了解更多信息,请参阅

避免在风暴期间和风暴过后出行

  • 不要去观光。游客会延误紧急服务并造成事故。.
  • 注意诸如
    • 路面积水
    • 受损的电力线
    • 山体滑坡
    • 损坏的道路
    • 倒下的树木或屋面板。.
  • 切勿冒险涉水。洪水中的大多数死亡和救援事件都与驾车涉水有关。.
  • 在未受洪水影响的路段,请慢行并打开车头灯。.

之后

  • 请继续收听 ABC 本地广播电台的最新消息、道路重新开放信息、社区会议等。.
  • 如果您离开了家,在紧急事务管理署(SES)或塔斯马尼亚警方告知您可以安全返回之前,请勿回家。.
  • 注意道路危险,例如路面上的泥土或碎屑、损坏的道路/桥梁以及正在进行清理和维修的工作人员。.

如果您的房屋遭到损坏

  • 在检查损坏时,请留在地面。注意倒下的树木、碎玻璃、松动的屋顶或其他危险。.
  • 穿结实的靴子、手套和防护服。. 
  • 在受洪水影响的建筑物内部,请使用手电筒,切勿使用火柴或蜡烛。. 
  • 饮用水必须煮沸,直到被告知自来水安全为止。.
  • 在经过持证电工或燃气技师安全检测前,请勿开启电源或燃气。.
  • 如果您的房屋受损,需要住到别处,请带上您的应急包和宠物。
  • 如果安全,请拍摄任何损坏的照片并联系您的保险公司。.

免责声明

The maps show potential flooding risks from consistent levels of rainfall across catchments, such as a 1% Annual Exceedance Probability (AEP).  In flooding events, rainfall is likely to be more inconsistent across a catchment, so these flood maps should be considered indicative only.  The mapped areas of flood risk show higher probability of inundation. Other areas have lower probability of flooding, but in severe and rare events (rarer than 1%AEP), other lower areas may be also at risk of inundation.
