Just further on the recent weather at Bretti, I consulted the Bureau of Meterology page on rainfall figures for the last 24 hours. Bretti only had 1mm of rain in the 24hours to 9am today, Gloucester had 3mm. If you'd like to monitor this just go to this page:

Each of the little dots is a reporting station, and you can find Bretti and Gloucester easily by placing your cursor on the blue dots around the Manning area.
So regardless of what is happening on the coast it is not necessarily an indicator of what conditions will be like at Bretti.
By Saturday we should have a much better understanding of what conditions will be like in that area for much of next week.
