I've no experience of it but it looks like a good PLL band B model. I don't know how easy they are to obtain in Oz but in Europe, Gilat AN8002 outdoor units (TX/RX) are sometimes on Ebay. They have good performance and include a polariser and feed. The AN8004 is band D but less common. Try a search here and on SatsUK to see how they have been used. In UK they are often around 20-50GBP but weigh around 2kg so shipping can be expensive.
s-band many thanks. The Gilat units look similar to Viasat units. Due to the popularity of Starlink many Viasat units are being discarded here. I will see if I can get the LNB in a Viasat unit working.
I'm not sure what Ka signals exist here, I think only Viasat, Inmarsat (?), and Military.
The viasat ODUs are very difficult to use as they have a complex control signal. I don't know of anyone who has managed to repurpose one. They are highly integrated whereas the Gilats have a normal LNB inside and can be used without mods, just ignore the tx part.
