Seems like some sort of price matching or some promotion the OEMs are running for the resellers.
Only for LiveConnected customers.
EDIT:
According to auna below:
Australian mobile virtual network operator (MVNO) Vaya has acquired 100-percent of competitor Live Connected for an undisclosed sum, with plans to continue running both mobile businesses as separate entities.The move adds Live Connected’s 25,000 subscribers to Vaya’s books, with the combined subscriber base for both MVNO businesses in excess of 70,000.The change of ownership should be invisible to Live Connected customers, with no shifts in rates or plan inclusions in the works at this time.

Liveconnected has been bought by Vaya so that makes sense why its available there
