SEASON25
WatchAFL Global Pass has 25% off a 12-month subscription at the moment. WatchAFL pretty much gives streaming access to Fox Footy for anyone outside Australia, or anyone who have a valid geo-dodging service (ie. Getflix). You can watch in full screen on a tablet and cast / airplay to your tv, or can watch on a laptop and connect it to your TV. I'm in Germany and the quality is very good (for me).
Normal price is $189AUD, so should come down to $141.75. It does say on the website that this is for 12-months access (rather than the remainder of the season), so it should take you through to this time 12-months. Be aware that it will automatically roll over at full price for the next season if you don't cancel in advance. I can't see how long the 25% offer is running for, but I can update the post if someone finds it.
For anyone overseas, Fox do give pricing in your local currency based on geo-location (normal price as either $149USD, €149, £149), so it's worth registering using a VPN outside US/GB/EU to get the Australian price which works out the cheapest.
If you want to support your club the international memberships often include Watch AFL.
e.g. the Adelaide 'Global Crow' membership includes a Watch AFL subscription, you also get a lanyard/membership pin/stickers and it's $155 for the year. Not as cheap as this but has those extras if you're a fan and some money goes directly to the club.
