Electronics retailer Dick Smith has launched post-paid mobile plans via Think Mobile.
Virgin Mobile has restructured its post-paid plans, cutting back to just five options for new customers.
Virgin Mobile Australia this week replaced its previous post-paid plan structure with a simpler collection of options.
The mobile roaming broadband provider now offers three styles of SIM plan, including local and UK-based 4G, with regular data access now available internationally in 84 countries.
Vodafone is offering its top-tier plan customers a freebie on international roaming, while Telstra customers can now buy a 'Travel Pass' to access local rates while overseas.
While mobile data usage alerts have traditionally been held back with a 48-hour lag, Telstra will now alert customers within seconds when they reach certain percentages of data use.
Vodafone has tweaked its mobile Red Plans, offering higher data limits and the ability to chew through unlimited data in the first 2 months of the plan.
Post-paid customers on Virgin have had excess data charges slashed, starting from today.
Optus customers will now be able to charge app, game and TV show purchases from Google Play directly to their monthly bill, without having to enter credit card details with every purchase.
Optus cuts handset subsidies and pushes up the price of mobiles, arguing similar moves from Telstra and Vodafone allow it to remain competitive.
