It is referring to English colonisation of Australia a few hundred years ago. The English did not learn the indigenous languages there, and they brought English law with them. It also refers to the fact that a lot of convicts were sent to Australia.

Joke: An Englishman gets off the plane, and immigration asks him if he has any criminal convictions. He replies “I didn’t know you still needed one”.

Yeah, not sure if attitude of english speakers toward natives in Australia is something to be widely joked about or satirized.

Bit late for that now, don't you think?

    "There's nothing I would rather be
    Than to be an Aborigine
    And watch you take my precious land away.
    For nothing gives me greater joy
    Than to watch you fill each girl and boy
    With superficial, existential shit.

    Now you may think I'm cheeky
    But I'd be satisfied
    To rebuild your convict ships
    And sail them on the tide.

    I love the way you give me God
    And of course the mining board,
    For this of course I thank the Lord each day.
    I'm glad you say that land rights wrong.
    Then you should go where you belong
    And leave me to just keep on keeping on."
