Arguably, Oz and New Zealand should be on this list since neither of those nations existed when the Poms colonised them. The Maori and Aboriginal people faced invasion, persecution and genocide, but one could argue they weren't nation states at the time. Unless you mean that you guys have invaded Oz to attempt to secure Ramsey Street here (to secure the valuable source of Neighbours episodes) and NZ whenever you make feeble attempts to compete against those glorious spartan warriors, the All Blacks, only to be beaten to a bloody pulp and shipped over here to recuperate in Erinsborough and to beg for forgiveness for your folly from your messiah, Paul Robinson...
