- 100 Mbps - $150 worth of points
- 245 Mbps - $160 worth of points
- $780 Mbps - $170 worht of points- 0

Optus will increases prices on all Prepaid plans from 28th April, matching Telstra's move in Oct last year.

they also increased prices on post paid plans during contracts several times over the past few years, even having the nerve to say 'well ackshually its not technically a 36 month contract you signed'.
Never will trust them again and will go out of my way to discourage people using them- 0

Anyone knows if Optus still give free Prime membership for 6 months ?

At least with the 5G product you can't return the modem if you terminate early, it gets 'paid off' in monthly instalments over 36 months and costs over $400, so bear that in mind if you're thinking of churning.

Better from Flybuys offer but carry risk that it won't track ?
