WHAT was bigger than Brexit and the Rio Olympics in 2016?

If you guessed the Western Bulldogs' drought-breaking premiership victory, you'd be right.

The Dogs' historic season and the AFL Grand Final ranked seventh on Facebook's most talked-about topics in Australia during a year that wasn't short on huge news stories.

The social media giant has released its year-in-review data, analysing and aggregating Australians' posts by tallying how many times a topic was mentioned on the platform.

Luke Beveridge's heartfelt gesture in handing the Jock McHale Medal to injured skipper Bob Murphy dominated much of the conversation among sporting fans.

Murphy later returned the medal to Beveridge, saying he could not keep it. The medal will be displayed in the club's museum.

The US election was unsurprisingly the most-talked about topic online, while Prime Minister Malcolm Turnbull also caught the attention of users.
