As an Android user, I've been in the market for a luggage tracker and saw that the official Tile online store has the Mate 4 Pack on sale for $67.99 (RRP $139.90). Standard sipping is $9, with an estimate time of 5-7 days for VIC metro.
For reference, JB Hi-Fi sells the Mate 2 Pack for $69.95: https://www.jbhifi.com.au/products/tile-mate-bluetooth-track…
Plenty of other Tile exclusive bundles for sale featuring the Mate, Slim and Sticker: https://www.tile.com/en-AU/products/tile-exclusives
Odd they don't have the pro's?
