i would say,start at carnarvon and work your way north.

 Any of the train stations in and around the metropolitan area, more crabs than you can poke a stick at, big ones little ones..... some as big as your head. No license required just a permit for the zone you are in. If that doesn't work, as Pendy said....go north young man!!!

 Kalbarri has a few

try balla balla about half way between K town and hedland airport creek and fields creek around K town forget about cleadervile (just north of K town) it gets hammered by the grey nomads

All the creeks on the eastern side of Exmouth Gulf hold plenty of the buggers, the hard part is getting them out

You have to cross the gulf by boat or negotiate miles of bush tracks and swamps on Uralia station [that is if Big Joe gives permission] to get there.

beach at carnavon and they would just follow the bait out of the water,and then we just grabbed them

Have heard of a few around Bunbury (Leschenault Inlet) and in Collie River near Australind, could save you a couple of hundred litres of fuel

No special license for them, just the RFBL if fishing for them from a boat http://www.fish.wa.gov.au/Species/Mud-Crabs/Pages/Mud-crab-recreational-fishing.aspx

I know someone who used to catch a few up north bring then down south release a couple in the collie river and eat the rest. Thats why they are down there and they are obviously going pretty good. 

 i wouldnt worry about salties until you get to about port hedland,the sea snakes are more of a worry though.

Hi All!
Another question!

What is the best mud crab trap to use from the shoreline and where would be the best place to buy good quality traps from.

Many Thanks
Kim

It would really helpful if someone can give me an accurate location or directions of where they last went and caught a few. I know everyone has their secret local spots. But for a first timer like me I would really appreciate being told of a place where I can definitely find these mud crabs.

 any where in the northwest that has mangroves and creeks.you can catch them with normal crab drop nets or you can walk in the mud flats and creeks and look for there holes and with a length of thin steel rod with a bend like a hook on the end you can slowly pull them out of there holes.you want directions,okay,take the port hedland to broome road and about 7klm before the degrey river bridge there is a station windmill track on your left,go downthis track until you see a line of mangroves to your left about 12 klm.leave the track and head for them,stop about 50 mtres  before.do not try and drive any closer or you will not get back out.walk through the mangroves with your steel hook and bag and you will come out onto a "beach" that is all mud.just look for small pools of water and you will see holes in them.put your steel rod into the hole and you will feel the crab inside,twist your rod around until the hook part is behind the crab and pull it out.takes a bit of trying to get it right but its pretty easy.if you are lucky and get there at the right time you can just walk along and pick them up,this only happens about twice a year.the place is called thelmas hole.be very carefull as they really bite and you are a long way from home.goodluck.sorry should have mentioned you take the old broome highway not the new one.

 mate the point of my post was that you can get mud crabs any where north of carnarvon where there is mangroves and creeks,you dont have to drive all the way to port hedland,but if you want to the distance is about 1870 klm from perth.you can camp there well back from the mangroves but i wouldnt these days with a chance a stray croc may be around.also depends who the station owner is.the two times a year differed from year to year but was always after a king tide.being that it is a two and a bit day drive from perth it would be a very expensive way to get crabs,but if thats your thing good luck.

 you can just park next to the creecks and throw your nets from shore . even had them coming out of the water to get some fish frames once at the ramp 

Another method > cram some stinky meaty whatever into a bait pouch of some sort ( Must be tough ) Weigh it down with something, attach a cord an chuck it in the drink. Leave it for 15 mins and SLOWLY retrieve, if it's a lot heavier than before its probably got a muddy attached to it. They are stubborn barstards they wont ( usually ) let go of it till near the shore. Use a rake or net to grab it just after it lets go right near the bank. Is an option when you cant get much of a vertical pull on your drop nets.

 Same drop nets as for blue mannas baited up and, TRAPS are illegal.....cant use em, end of story. If you wanna go hooking em out of a hole thats good or pick em up walking on the mud flats or as everyone has said above. Great fun, get into it and find em thats what its all about :-)
