For all our combined complaints about Aussie domestic airlines, we have it pretty good in comparison to many airlines / countries. BA examples a plenty.
In the US an "F" seat on AA for nearly 3 hrs and water and small packet of crisps or peanuts, no IFE.
A 3.5h flight in a Y seat YYC to ORD and there was one 200ml bottle of water per person. No snack, no second bottle, no IFE, no magazines.
A few years back, I recall a seat on LANd where the FA announced they were serving breakfast. A chocolate wafer, a chocolate biscuit and a square of chocolate with the option of accompanying flat Coke or Fanta or water served from 2l plastic bottles that I'm pretty sure had been opened on a previous flight.
