Not likely australia has an even worse track record than america. They will support it because it will hopefully take some of the heat off of there own abysmal record of bigotry and apartheidism. One only needs to point out australias own criminal activity with the naura prison, the Deportation of any one the police do not like to christmas island. The detention, torture and murder of indigenous people.
And now for a dose of reality
We are now living in 2017 and no Australian in their right mind denies that much of the treatment of our indigenous people was appalling at best
However, numerous initiatives aimed at reconciliation, compensation and bestowing rights to aborigines have been implemented since the 1970s.
To be fair, some are misguided whilst others are mere band-aids but to equate modern day Australia with an apartheid-style regime is nothing short of nonsense.
As for Christmas Island, you need to check your facts as the vast majority of detainees are visa holders that have forfeited their rights to residency by being convicted of crimes punishable by a minimum of 12 months in jail
Nauru and others are different in that the detainees are all there because they attempted to enter the country illegally and have virtually no evidence to back up their claims.
It obviously is far from perfect but better than having a free for all where anyone that washes up on a beach is granted residency and goes straight onto welfare
Furthermore, having lived in China and the Middle East plus travelled extensively, I can assure you that Australia is nowhere near being the most racist country on earth.
In fact, we would be lucky to get out of the heats let alone finish on the podium.
Lastly, I suggest you look into your own back-yard before criticising ours.
Does the genocide of the Moriori people ring any bells?
The death of more than 50% of the Maori population by 1900?
How about the confiscation of lands, destruction of culture and economic suppression of the Maori people that was commonplace until the 70s?
Sounds like we have more in common than you would care to admit
