Thanks to Possum1 and the lead provided, Gayndah should be appearing in your EFB fairly soon. I've spoken with the council whom weren't aware of OZRunways and Avplan so were delighted to have them appear in the apps in the interests of letting all pilots have access to them.
I have also been in discussions around knowledge sharing to get an addition 4 or more units set up at other airfields within the councils boundaries. Stay tuned on those, however they will be a little while off whilst a technical solution is sorted.
