Sorry guys, maybe I was really lucky! Eh, disappointing.
I got the bags from the shop at The Glen (Springvale Rd, Glen Waverly).
I've bought the dry food from the Richmond store before, and I'd expect that store to discontinue it as well (that's what happened when Eagle Pack was discontinued - both stores no longer carry it).
The cans are small sized, maybe around 500 g, and are not discontinued (yet) as far as I could tell.
