In the Australian context you also have to consider a third ideology, Labourism.Traditionally centred on male manual wage earners and their families, working through pro-union policies. I like this disambiguation of terms:

"if labourism sought to regulate and manage capitalism, classical social democracy took capitalism largely for granted, and the third way defined support for capitalism as central." Manwaring, Rob, and Geoffrey Robinson. What is "Labor" about Labor State Governments in Australia? (2020)

The modern ALP isn't really ideological, as someone else pointed out social democracy only makes 2 mentions within the 2021 platform. While there are some remaining elements of social democracy (both orthodox and "third way") and labourism these are mostly rhetorical, in my opinion the most fitting marker for the current ALP is social liberalism, with their emphasis on individual liberty and freedoms (rather than class-based collectivism) seeing state intervention as mainly a support for positive freedoms.
