looking for the does and dont's when fishing King sound.

I was told that the tide must either be half way down (or up) to use the boat ramp for one but someone pointed out that Fraser River is a spot to check out, is it ok at the mouth of the Fraser on low or would I be hitting mud?

Just looking to do a trip around the 5th if it's possible with tides etc or it maybe a shorter trip to Broome.

Thanks in advance.
