Yay another Aussie. You sound pretty similar to me, as do your numbers.
Answer for me was to pile on some weight, and method that worked for me was to do GOMAD for last 3 months, on top of all the food you already listed.
Everythings going in the right direction now (weights up to 95kg, lifts going north), except for bodyfat. But that'll fix itself up when I'm stronger.
