去塔斯曼尼亞一問

由香港到悉尼，再由悉尼到塔斯曼尼亞要乘同一間航空公司，例如澳洲航空公司(Quatas)，這樣才有保障。

訂機票時是由香港到到塔斯曼尼亞(e.g.Hobart)，在悉尼轉內陸機。
e.g.
21:10 HK -> 07:55 Sydney
14:20 Sydney -> 16:10 Hobart

航空公司會為你預留足夠轉機時間。因為是Connecting Flight 航空公司是有責任送你到目的地。如果因航班延誤，航空公司會為你安排，不用擔心。如果入境時延誤，記得事前先通知航空公司，好讓他們作出安排。

入境的程序是：
Transfer between Terminals -
Transferring from T1 (International Airport) to T2 and T3 (Domestic Airports):
After you clear customs, recheck your baggage at the Seamless Transfer Check-in counters and then board the shuttle bus for the Domestic terminal.* The shuttle bus service is available to passengers that are travelling or have travelled on a Qantas flight (including codeshare flights) or oneworld flight. It operates from 6am to 12noon every 10 minutes and from 12noon until 9.40pm every 20 minutes. The bus arrives at T3 opposite Gate 1. Check the screens for departure gate information.

when you buy the air ticket in HK, you should buy HK to Tasmania ticket, and stop over at Sydney. It should be cheaper this way, and also, if you miss the tasmania flight, the airline would arrange the next flight for you with no extra cost. For your ticket is to Tasmania.

一定趕唔到，因為由香港去悉尼d飛機會係international terminal降落，而sydney - tasmania d飛機會係domestic terminal起飛，兩個terminal之間車程都要10mins. 另外，過immigration同清關都唔快。

tasmania其實幾時都唔係旺季，唔方多人，如果去到機場先買飛會好貴。一日有好多班機由sydney- tas，搭班晏d唔駛咁趕。

5月澳洲係秋天，太陽會5-6落山。

如果香港到悉尼航班延誤,你就趕不上到tasmania的機了.
到悉尼機場先買票這個問題答不到你,要看當時情況.我會建議你乘搭下午3時以後的飛機,這樣可行性會大些.

5月份南半球是秋天轉冬天,日照時間會慢慢減少.
