Hi,I havent been to Phuket for about 10 years but make sure you have transfers from the airport to the beach area as it is quite a distance.
If the traffic hasnt become like other places in Thailand then hire a scooter and ride back into town,the hill you have to climb is a bit hair raising but a real experience.

I am also from Perth but forgot to fill in my details when I joined a few days ago.

Are you having a stop over in BKK on the waay home?I couldnt go to Thailand without at least 3 days in BKk,its a great city once you find your way around.

Have a great time.
