Crocs on the move
Wuz just talking to a Maryborough local, apparently a healthy population of 3m lizards in the Great Sandy Strait now. Be interesting to see if they start showing up in Moreton Bay in numbers. Might be like the explosion of big threadies in Brisbane.

Re: Crocs on the move
Hi Matt
Don't know about a healthy population of 3m crocs in Sandy Straits.
There were 2 about that size in the Mary River (flows into Sandy Straits) that proved elusive for quite a while. They were travellers not breeders.
If there are any in the Straits they'd also be travellers.
There are very few areas suitable for breeding south of the Fitzroy at Rockhampton.
Even the salt below the Rocky barrage is restricted.
I've seen baby crocs collected in a cardboard box from the grassy brackish water in Gavial Ck just on the downstream side of town. 2 females live in that creek with a big male of approx 4m living in the river mangrove area opposite the mouth. Tick Tock is his name given to him on the basis that its just a matter of time before something happens. All 3 are seen at different times in dry times going up through town reach to fresh water from the fish ladder at the barrage.
Have never seen baby ones in the salt part of the river apart from the above. Simply very little suitable breeding areas.
Up above the barrage is a completely different story.
Excellent breeding terrain with plenty of quiet wet grassy areas and fairly regular flooding. Small crocs get a free ride with a river fresh down through the barrage into the salt where there's an existing population with which they have to compete for territory. Not always successfully so they keep moving. High turnover of crocs up to 2.5 metres in lower Fitzroy.
They go south along coast mainly although some have been spotted off Emu Park/Yeppoon beaches at times. There are no real beaches to the south (or people living on waterfront (apart from Tannum Sands) until you get to 1770/Agnes Water. Therefore there's nobody to spot them going south.
Nephew caught one at Tannum Sands in crabpot not long ago. Juvenile one probably heading south.

Great info Ron
Just relaying what a Maryborough fisho told me, he reckons people have to be a bit careful around there now.
