You have no home life as a truck driver and it sucks. There's also a difference between starting $105k and ending $105k. $105k was graduating salary, and I graduated with no debt, and I sit at home all day in my air conditioned room typing on a computer.
On top of that, I can google an Australia Truck Driver salary, it's average of $25-$35 an hour. Awful.
On top of that, 105,000 AUD is equivalent to $78,000. Pretty terrible top end salary to say the least.
Stay mad.
