How do I travel from Australia to Samoa islands?

Quantas, Air NZ. Or go to your local travel agent, they should be able to fix you rightup. By plane or hey if you want cool, try by cruise liner :)

Go to Webjet - http://travel.webjet.com.au/webjettsa/home.aspx?EntryPoint=Flight

Here it will search ALL airlines flying from Aussie to Samoa and give you all the prices on one page for comparison

Search from Auckland - NZ also, sometimes it's cheaper to fly there, then onto Samoa (sister-in-law told me this)
