Try googling for "the all-in price" and you find plenty of examples, although more or less none for Australia.
"the all-in price only rises to £598pp." http://travel.timesonline.co.uk/
"you may be able to shave a couple of hundred pounds off the all-in price" http://travel.guardian.co.uk/countries/
"The all-in price of £27.50 per head (including VAT) includes one bottle of wine between 2" http://www.scoutbase.org.uk/library/hqdocs/tp...
There are actually quite a few hits for US sites too:
"The all-in price for the scheduled portions of the program is $US 400 per person " www2.aya.yale.edu/classes/yc1962/viewpoints.html
"For the latter, the all-in price of the bundle is likely to include what the customer perceives as a penalty component." http://jmis.bentley.edu/articles/v20_n2_p5/
