They had issues with winter weather moving the sand around, but the dredger is back: www.gippslandports.vic.gov.au/notice-alerts/notice-to-mariners-and-warnings/

There is no real shelter east of LE until Gabo. Mallacoota has a small jetty and bay but not fantastic for yachts, and I've never been in close there. I've anchored behind Gabo, but had a swell, but a poor sleep was better than no sleep. There might be shelter at Bittangabee Creek, depending on your draft, otherwise several spots near Eden are much more secure. Be prepared for a 100 mile sail - so you need to be equipped and trained, but it's quite doable in good weather. And the coastal scenery along the Croajingolong coast is fantastic. Just steer clear of Beware Reef.
I'll send you a pdf if I can.
