An $800,000 government advertising campaign about the dangers of flooding in Sydney’s west has been described as a thinly veiled PR strategy to garner support to raise the Warragamba Dam wall.

As Sydney water levels reach their lowest point in more than a decade, the ‘Get Ready for Flood’ campaign has been launched.

The campaign includes billboard advertising and online campaigns warning of the dangers and likelihood of flooding in the Nepean-Hawkesbury basin.

While Minister for Western Sydney Stuart Ayres said “Noah built the ark before the flood,” opponents have questioned the timing of the $780,000 advertising strategy.
