Rain risk in Sydney, month by month
Sydney averages 15 rain days in March and 6 in August. A rain day here is any day with at least 1 mm of precipitation, averaged over 2015–2024. The risk columns assume every exterior day can be lost; the cover-day column is what you need to be 90 % sure a five-day exterior block finishes.

When to shoot exteriors in Sydney
Weighing daylight against rain days, December comes out best: 14 h 23 min of daylight, 10 rain days and 11.6 hours of sunshine a day. The sunniest month is December (11.6 h a day).
The month matters here: five exterior days run a 66 % risk of losing at least one day in August, but 96 % in March — 2 against 4 cover days for 90 % certainty.
Rain days are not grey days: even in March, the wettest month, the sun shines 9.5 hours a day on average. Many of those rain days are wet for an hour, not all day — if your scenes can wait out a shower, lower the share slider in the tool.
