I’d try other specialty bed linen stores like Bed Bath N Table.

Give Ezibuy a try they have lots of non standard sizings

I’m not sure if you’d have to try king sized fitted sheets.

I would ring around certain dept stores such as Myer, Harvey Normans etc .Not sure if Target or Big W would have them either .

When buying sheets look at the depth of the product you will be surprised that some are way deeper than others if you hold the product descriptions side by side. I always buy the deeper ones for our king size bed..

shop online – that’s always a good way to go.

Try Target. They have a great range and they fit my bed.

my house,shop online or at the store,i think you will find that it’s a newzealand size that we have an equivilant for,or they will be able to order/send you in the right direction

keep an eye on ozsale as they have the king size and super king size and measurements, pricing is always good,

Target are the place to go, they fit mine.

Try looking to Pillowtalk or Spotlight.

I get mine from Target and they fit my pillow topped mattress

our sheets are from myer and they fit

have you tried house ?
