Cheap 1TB MicroSD card. I went into Officeworks today to price match. The SanDisk Extreme model is also relatively cheap.

FYI Bunnings & OW 1TB SanDisk Extreme listings are different products (SDSQXA1/SDSQXAV respectively). AV is latest with higher write speeds. Nearly got it with a less techy salesmen.
