Australian Construction Work Done (Q2 QQ) -2.1% vs. Exp. 0.5% (Prev. 3.4%)

Construction work done is the more followed of Australia's two quarterly construction inputs to GDP, and a swing of this size from expansion to contraction typically feeds through the building and engineering components of the national accounts rather than surprising on its own, since partial indicators like building approvals and capex intentions usually precede it. The distinction worth drawing is between residential work, which tracks the approvals pipeline with a lag, and non-residential and engineering work, which is driven by public infrastructure timing and mining capex and can be lumpy quarter to quarter. A miss of this magnitude raises the contribution question for the GDP print that follows, though construction is only one input and episodes of weak quarterly construction have historically been absorbed without derailing the accounts when household consumption held. The RBA read-through runs through the labour-intensive nature of the sector and what softness implies for the pipeline of dwelling supply, a recurring tension in Australian rate deliberations. The follow-ons are the composition breakdown in the full release and how the print squares with the preceding approvals data.
