NSW DPI has recently produced a number of videos on DPI issues and permitting aimed at local councils.
DPI Fish Friendly Councils: Obstructing fish passage - Waterway crossings, weirs and other instream structures can limit fish migration and therefore reduce their chances of survival. Discuss your proposal with DPI Fisheries before designing waterway crossings and other instream structures.
One of these videos is focused on fish passage, and features the use of bridges including InQuik: https://www.youtube.com/watch?v=EA5zpk8nb-I&ab_channel=NSWDPIFisheries
Other informative videos can be found on the NSW Fisheries YouTube channel, including dredge and reclamation requirements, harming marine vegetation, and permitting: https://www.youtube.com/user/NSWFisheries/videos
