Wallabies flanker David Pocock has posted a dig at Tony Abbott's speech to a Conservative gathering in London on social media.
Pocock, who is never shy to put his political view forward, posted a wry tweet about Mr Abbott's suggestion that the Biblical commandment "love thy neighbour" did not apply to refugees.
During his speech Mr Abbott lectured European leaders on how to stem the flow of refugees from Syria and elsewhere in the Middle East.
"Implicitly or explicitly, the imperative to "love your neighbour as you love yourself" is at the heart of every Western polity," Abbott said.
"It's what makes us decent and humane countries as well as prosperous ones, but – right now – this wholesome instinct is leading much of Europe into catastrophic error.
"All countries that say "anyone who gets here can stay here" are now in peril, given the scale of the population movements that are starting to be seen.
Responding to a post from ABC journalist Julia Baird, Pocock tweeted:
In his tweet, Pocock incluced a video of American actor Will Ferrell playing George W Bush praying.
"We thank you for everything you do and we want you to remind everyone in this theatre that by participating in this prayer they have automatically accepted Jesus Christ as their Lord and saviour regardless of their religious beliefs and can't get out of it no matter what," Mr Ferrell said in the video.
Pocock regularly airs his political views on social media and elsewhere.
In the past Pocock has been outspoken in his support of same-sex marriage, declaring in 2013 that he would not marry until same-sex couples could.
He is also one of 61 signatories to a letter calling for a moratorium on all new coal mines, which will be presented to the Paris climate change summit.
Pocock has also used his Twitter page to decry the approval of the Shenhua coal mine, to spread the word about Save the Rhino Day and to promote the Australian Food Sovereignty Alliance, which calls for a more sustainable food system.
