Bicheno to Triabunna and surrounds flood guide - Tasmania State Emergency Service

Riverine and flash flooding information for communities around puthimiluna/ Great Oyster Bay on Tasmania’s East Coast

Version 1.0 October 2025

Bicheno to Trinabunna flood map - overview

Flooding from intense rainfall can cut the Tasman Highway in multiple places. This flooding could be

deep
impassable, and
potentially dangerous.

The Highway may also be cut in places to the north and south of this plan. Inland alternative routes are

also likely to be cut, and
can be more isolated and dangerous.

Flood can isolate communities and properties along the coast for a short time. Waterways in the area are short, so flooding is likely to be for hours rather than days after rain stops.

本指南中的地圖顯示了每年可能發生的%機率的洪水警戒等級。您一生中很可能會經歷地圖所示的洪水。塔斯馬尼亞居民需要為不常發生但可能發生的洪水事件，以及他們可能已經經歷過的低窪地區洪水做好準備。.

Even if your home is not flooded you should prepare for

isolation
potential power and telecommunications outages.

The Tasman Highway may be cut in multiple places during a major flood event, depending on where the rain falls and how heavy it is. Travel in the area is likely to be difficult or impossible until roads are clear.

Floodwaters will likely isolate many areas along the East coast for a few hours at the most. If you are safe at home or elsewhere, it is usually best you stay where you are until the flooding subsides. If you need to evacuate, you should leave early, before flood waters rise. Flood waters are likely to disperse quickly, once rain stops.

您有洪水風險嗎？

East Coast Lows can often bring intense rain that sometimes leads to flooding in areas along Tasmania’s East Coast. Significant local flooding events happened in 2016, 2011, 1974, 1969, 1923, 1922, 1914, 1911, 1876, 1972 and 1870

我應該做什麼？

檢查地圖，看看您的住宅或企業是否可能遭受洪水侵襲。.
評估您的住家或公司，並做好準備以盡量減少潛在的洪水損害。.
檢查您是否能在洪水期間安全地抵達家中、工作地點或學校。.

中央氣象局預報、警報與觀測

本局發佈 洪水警报、恶劣天气警报和/或雷暴警报，可能因强降雨引发山洪暴发 每當大雨可能會在某個區域出現。從發布預警到豪雨發生的時間，可能從一小時到二十四小時不等。.

Whenever rain that may lead to flooding along the Swan River or Meredith River is expected, the Bureau will issue a Flood Watch – a “heads up” early advice of forecast weather that may lead to flooding. There are no formal warning levels for waterways in the area as the river systems are too short.

雨量觀測 at places such as

Bicheno
Friendly Beaches
Swansea, and
Lake Leake

can indicate possible flood risks. Given the very short warning times, it is best to act on the BoM warnings rather than wait for any flood alerts during rainfall.

這 Mt Koonya Radar is useful to be aware in real-time where heavy rain is falling for the areas south of Swansea. Radar Rainfall estimates can also fill in gaps in areas where there are no rainfall stations. The North East of Tasmania is not well covered by BoM radar.

了解警告和關鍵資訊

隨時留意周遭狀況。定期查看天氣預報、觀測數據和警報。.

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.

Minor flooding can impact low-lying agricultural land. Livestock and equipment near waterways should be moved. There may be low level flooding across some roads, particularly (from North to South):

Rosendale Road access to Apsley Gorge, parts of the Campground/ picnic area
Tasman Highway
- South of the Lilla Villa Bridge
- North of Lake Leake Road
- South of Springvale Road
- North of Meredith River
- Near Sandy Creek, Mayfield Beach
- Near Trehawke Creek (Buxton River area)
- North of Lisdillon Rivulet
- South of Little Swanport River
- Near Ravensdale Rivulet
Lake Leake Road near Whelans Bridge
Coles Bay Road East of the Tasman Highway junction (Apsley River)
Glen Gala Road, Cranbrook
Grange Road, Cranbook
Some properties around Llandaff may flood, along with nearby property on Coles Bay Road. There are several low-lying properties along the Tasman Highway that are flood prone.

嚴重洪水

Rainfall of about the following amounts will cause major flooding in the area. This level of rainfall has a 2% chance of happening any given year (based on rainfall records at Swansea up to 2016).

35mm in 1 hour
45mm over 2 hours
54mm over 3 hours
77mm over 6 hours
113mm over 12 hours

Key transport routes most likely to flood include (from north to south):

Tasman Highway, many places, but particularly
- Between Bicheno and Apslawn
- Extended areas around Cranbrook
- Near the Cygnet River, south of Cranbrook
- North of Lake Leake Rd
- Around the Wye River, south of Crossins Road
- North of Meredith River
- Near the mouth of Saltwater Creek, Swansea
- Near Stony River, south of Swansea
- Around Buxton River
- South of Little Swanport River and north of Ravensdale
- North and south of Triabunna.
Rosedale Road – access to Apsley Gorge
Coles Bay Road
- Near the junction with Tasman Highway
- Around the Friendly Beaches Road junction
- Near Swanwick
Old Coach Road river crossings
Glen Gala Road, Cranbrook, extended areas
Lake Leake Rd near Whelans Bridge
Crossins Road
Grange Road several places
Swan River Road access to Dolphin Sands
Esplanade area, Swansea, and some areas around Maria Road
Freestone Point Road near the intersection with Tasman Highway

Aside from key routes prone to flooding, properties and some campsites in the area that are prone to flooding. Of most concern (from North to South):

Apsley Gorge waterhole access and campground
Landaff riverside properties and some nearby properties on Coles Bay Rd
Low lying areas northern parts of Swanwick, which may also be impacted by coastal inundation
Cranbrook properties near Glen Gala Rd, Grange Rd, Springs Road and Tasman Highway
At Swansea, Saltwater Creek may flood
- Maria St
- several properties on River Street, and
- the Esplanade area, especially at high tide.
At Triabunna, the Esplanade area. This area is also prone to coastal inundation.

Storm water runoff (overland flow) can affect other properties after intense rainfall.

了解你的風險，做好準備，盡可能降低風險，與他人聯繫，保持警惕並安全行動。.

洪水之前

1. 認識你的風險

塔斯馬尼亞經常發生洪水，可能造成廣泛且嚴重的損害。在過去 200 年裡，塔斯馬尼亞有 78 人死於與洪水相關的事件。本指南旨在幫助您了解您所在地區的洪水風險。.

2. 準備您的家戶

制定包含風暴和洪水應變計畫

思考一下在風暴或洪水來襲時你會怎麼做，意味著你準備得更充分，每個人都會更安全。制定一個家庭中的每個人都理解的緊急計畫。有檢查表可以幫助你思考你的計畫——請參閱為緊急情況做好準備 – 為個人和家庭準備應急措施的指南。.

定期檢查您的計劃，並讓家中的每個人都設想一次可能影響您家的洪水情況來進行測試。.

準備一個緊急救生包

準備好了

電池供電的收音機和手電筒，備用電池
重要資訊，例如您的緊急應變計畫
緊急電話號碼列表
食物和水
急救箱
橡膠手套或堅固的皮革手套

需要時打包

暖和的衣服、結實的鞋子或靴子
藥品、眼鏡或其他必需品
手機和充電器
寵物食品和他們需要的任何其他東西
照片和特別紀念品
錢
重要文件，例如
- 保險文件
- 護照與
- 出生證明

定期測試收音機和手電筒的電池。.

3. 在可能的情況下，降低您遭受洪水侵襲的風險

在購買、維護或開發房地產時，請考慮風暴、洪水和其他災害。.
修剪或移除您家中、商家或您家附近有電力線的樹木和樹枝。.
保持您的排水溝和排水管暢通。.

4. 與他人建立聯繫

認識你的鄰居並參與你的社區。一個緊密的社區，在緊急情況下更安全、更有韌性，並有助於每個人在事後更好地恢復。檢查家人和鄰居是否安全，並了解正在發生的事情。.

期間

5. 保持更新

隨時留意周遭狀況。定期查看天氣預報、觀測數據和警報。.

6. 保持安全

監督兒童.
為可能的停電、停水或斷網做好準備。.
檢查您的緊急救助包是否已準備就緒。.
切勿靠近淹水區域，例如排水溝。. 永不在洪水中有行走、玩耍、骑行或开车。你無法確定水下有什麼，或水有多深、流速有多快。20公分的湍急的洪水就很容易將人沖走並淹死。洪水可能很危險。.

您的房屋可能發生淹水時

將家居物品放在高處，以盡量減少潛在損壞。.
如果安全的話，請關閉水電和瓦斯。.
一種防止污水倒灌回屋內的好方法是將沙包放入塑膠袋中，然後用它們來堵塞馬桶、蓋住排水孔和水槽。.
趁你還能安全脫困時趕快離開。.

如果你需要疏散

請遵循 SES / 塔斯馬尼亞警方的建議。.
帶上你的緊急求生包。.
前往朋友或家人較安全的地方，或前往疏散中心。.
讓別人知道你去了哪裡。.

照顧好你的動物

在緊急情況下，您有責任照顧您的動物。如果您有寵物和其他動物，在洪水或其他緊急情況下，疏散的時間會更長。在洪水可能上漲之前，請及時將牲畜移離易受洪水影響的地區。更多資訊請參閱

請避免在風暴期間和風暴之後旅行

不要去觀光。觀光客會延誤緊急服務並造成事故。.
注意危險，例如
- 路面积水
- 損壞的電力線
- 山崩
- 損壞的道路
- 倒下的樹木或屋頂鐵片。.
切勿駕車通過淹水區域。洪水中的大多數死亡和救援事件都與駕車通過淹水區域有關。.
緩慢行駛，並在不受洪水影響的道路上打開頭燈。.

之後

請持續收聽 ABC 地方電台的最新消息、道路重新開放、社區會議等資訊。.
如果您離開家，請勿在聯邦緊急事務局 (SES) 或塔斯馬尼亞警方告知您安全之前回家。.
注意道路上的危險，例如路面上的泥沙或碎屑、道路/橋樑損壞以及正在進行清理和修復工作的工人。.

如果您的房屋已受損

在檢查損壞時，請待在地面。小心掉落的樹木、碎玻璃、鬆動的屋頂或其它危險物品。.
穿著堅固的靴子、手套和防護服。.
請使用手電筒，切勿在受洪水影響的建築物內使用火柴或蠟燭。.
將所有飲用水煮沸，直到被告知自來水再次安全為止。.
在經註冊電工或燃氣技師測試安全之前，請勿開啟電力或燃氣。.
如果您的房屋受損，需要暫時住在其他地方，請攜帶您的緊急應變包和寵物一同前往。
如安全，請拍攝任何損壞的照片，並聯繫您的保險公司。.
監督兒童.
檢查鄰居是否安好。.

免責聲明

這些地圖顯示了跨流域的持續降雨量所造成的潛在洪水風險，例如 1% 年超越機率 (AEP)。在洪水事件中，降雨量在流域內的分布可能更不均勻，因此這些洪水地圖僅供參考。已繪製的洪水風險區域顯示淹水機率較高。其他區域的淹水機率較低，但在嚴重且罕見的事件（機率低於 1% AEP）中，其他較低的區域也可能面臨淹水風險。.
