Background
It is illegal in Australia to operate, supply or possess a GPS jammer; the communications regulator, ACMA, gives the maximum penalty as a fine of up to $330,000 and two years in prison per offence (ACMA). A Melbourne taxi driver was fined $850 for using one after a joint campaign by ACMA and Victoria's taxi regulator (iTnews). For the reporting on interference in Australia, and who it is attributed to, see Oceania.
Only hexagons whose centre lies inside the borders of Australia are counted, so hexagons in neighbouring countries and out at sea are left out. The map is framed on 43.7° S to 10° S and 112.8° E to 153.7° E.
Australia is counted under Oceania.
