Are Sydney Anglicans actually Anglicans?

Michael Jensen defends Sydney Anglicans based off Anglican tradition: Are Sydney Anglicans actually Anglicans? – Opinion – ABC Religion & Ethics (Australian Broadcasting Corporation):

There is for Anglicans a core of orthodoxy around which all manner of stylistic variations are permitted and even welcomed. The needs of mission and local custom make liturgical flexibility desirable - a practicality that the Anglican formularies of the sixteenth century themselves recognise.
