newbiest_user,
You know what laptops are available in Australia and I am afraid that I don't. You need to do your own research locally within your price bracket.
This is a very general article that I found from Gizmodo Australia:

You sound like you have a pretty good dual-boot setup with W7 and openSUSE 13.1 at the moment.
Why is there a need to throw $800 at a "solution"?
I would hesitate at recommending W10, since out of all MS's systems I like W7 the best but that is a personal preference.
Nevertheless, you can upgrade from W7 to W10 for free if you wish, but you have about another 10 months in which to take up that offer.
Another idea would be to use Linux on your existing laptop and have W8.1/10 on your new one.
The person in the computer shop is unlikely to have heard of Linux, unless you are really lucky.
You could be very cheeky and take your openSUSE 13.1 DVD (or USB stick) with you to the shop and ask them to boot a demo machine.
It is important to check that the laptop's
wifi works with Linux in addition to any other hardware.
Do try and obtain
precise details of the exact chipset which is used in any particular laptop.
Some
Realtek ones are noted here:

There can be major compatibility problems with wifi in Linux, so do be careful and use Google to find out whether a particular chipset will work, possibly after some tweaking.
Of course you can always fit a Linux-friendly USB wifi adaptor but this is often unsatisfactory because of potential loss, damage and theft.
