GLENELG Highway users between Casterton and Mount Gambier continue to play Russian Roulette with wildlife and logging trucks and machinery, despite road authority assurances that problem vegetation would be dealt with.

Coastal (or sallow) wattle, while not a declared pest plant, was identified in a 2018 South Australian Natural Resources South East group report as problem along both the Casterton-Penola Road and Glenelg Highway between Mount Gambier and Casterton.
