Well I've tried with my Android TV Box with built in Sat and UHF Tuners and can't. I think a much larger dish is required. Probably 1 metre or larger.

They're also 16APSK which a standard decoder won't receive according to my limited knowledge.

Pretty sure you can't get those channels with standard sky dish.  If you have no luck with satellite, you can get all the Australian freeview channels via Kodi and the right add ons.

New Zealand is covered by FNANZ and FNZA and FNZB footprints

ABC and SBS are on the FNB footprint which only covers Australia. 

As above those 2 transponders are on an Australian ONLY beam.

Thank you for your information.

Please explain how I can add the australian channels to my IPTV with kodi.

I have m3u which lists the SBS and ABC channels but none of them work.

Some Australian streams require a smart DNS proxy provider to enable you to use them as they're geolocked to Australian IP addresses.

You can use the Freeview FV app http://www.freeview.com.au/freeviewfv/ to watch those channels (plus Seven, Nine, and occasionally Ten content). It has Chromecast support so you can watch them on TV. The ABC iView and SBS On Demand app can be used for catch up, and also has Chromecast support. Works well for me.

So as it happens, my sister has a giant dish on the front lawn in the house she is renting. I'm talking several metres across. It's an eye sore. Nobody uses it. What would be the purpose of that dish and could I pick up those Australian channels?

Those dishes are most commonly installed by the Asian's to pick up channels from home.

The big dishes tend to be C band and usually won't pick up (Australian) Ku band channels without some modification - if at all.

1) It is most probably not pointing at the right satellite.

2) If it is made from mesh it won't pickup Ku Band as good as a solid dish and if the mesh holes are too big, it won't pick up Ku at all. 

3) You will most likely need to change the LNB from a C to a Ku.

4) All going perfectly you may still not collect enough signal to view the channels given that the beam you are trying to receive is not intended for/aimed at N.Z.

Before spending any money you can measure the diameter of the dish to work out theoretical Ku band gain, look at the satellite beams foot print to determine signal strength at your location and use online calculators to see if your dish has got sufficient theoretical gain for success or not.

I've talked to guys who do this successfully and 4 meter solid dishes and high quality LNB's are sometimes what is needed. Maybe someone on here has succeeded and can tell us what they used.
