The Liberal MP for Cook Simon Kennedy (yes, I had to look up his name because I forgot) asks the same question:

Tomorrow it will be 1000 days since the election where the Prime Minister promised life would be cheaper under him. Instead, food is up 12%, gas, 34%, rent is up 17% and Australian families have paid $50,000 more on atypical mortgage. Why won’t the Prime Minister apologised to Australians for his weak leadership, bad decisions and wrong priorities?

Same answer, different bucket.
