I have no reference BUT I believe that may be well out of date, should be more like $130 today!
No, it is about $94. It goes up with CPI each year.
The reasonable amounts for travel expenses with a salary below $84,250 from the ATO website are:
B'fast $19.60
Lunch $21.95
Dinner $37.80
Incidentals $14.95
If you get more than the reasonable amount then the entire amount must be shown on your group certificate and is potentially taxable.
