Travel Tips for travel in Fiji and Australia

Need airfare to Fiji, what does it run from the US or Australia? Ask the Oz experts. Is it safe to drive? Which side of the road do you drive on? I only have a week, I was planning to drive from Sydney to Cairns; is this doable? Would you do it? Should I fly, are there commuter flights?

Hi, my first post here. I want to determine how to use credits for air fare from California to Sydney, Australia. We are going to take a New Zealand cruise leaving from and returning to Sydney. Then we will need to fly back to California. Any suggestions are greatly appreciated. Thank you.
