Hi. Thanks for all your responses.
After speaking with the importers, there was only a couple of tyres in the country in other states. After paying freight for the tyre and given a timeline of up to 2 weeks, i decided to wait for a shipment due in Melbourne which only added an extra week. As this is our second car i thought no use in paying extra for only getting it 1 week earlier.
I have placed a tyre on backorder.

I cant wait till i need to change all 4 tyres so i can pick a tyre that is a bit easier to source

Thanks again,
Crispy.
