300m line is where you want to start, we found them in 300m on a drop off to 330m, and 330m down to 360m. Litterally straight drops you will see the fish on the edge.

Didnt look too much south of the light house, straight out from the light house and north found some all mighty big lumps and ledges in 300-400m of water.

We baited fished for them, however given we were out just before the high probably could have dropped a jig down into them as the drift was pretty slow.

Thanks for the info  

 this sought of info has just in the last few hours become very relevant to me    

hope you nail a few stick faces and find the ruby tuesdays 

 or holiday - either way lucky you.

 Hey Paul, as Bodie said 300m very good depth to start fished that dept for good success few months back. If you do put in around tandas we fished mainly south from there oposite direction to Bodie and found plenty. Generally you find 1 you find lots !!!!

Definatley look for a depth change I found fish sitting at top of lumps. good luck .

Also good luck to Gilly when you head up there would highly reccomend using lights on the rigs.

Regards Humpback

 Gilly - where's exmouth ;)

We've got lights organised - have heard no lights = no fish over 250metres.....

paul, let me know how ou get on mate as Ruby's on my list too after many years thinking about it....looked at doing myself a few years ago and heard that: due-SW baring from north passage tantas was goer on 400m line and also heard 300m line due-west of closest oil rig to murions.....that's obvious pretty vague but is best / clearest info I could get from guys coming in with them every day.

 How far out is 300m up there guys?

 Hey sea-kem from either passage not that far compared to Metro. Without checking my plotter i think about 20kms (Freo to rottnest) max

mate without getting out the chart I can't give you exact distance but it's real close mate -  ALOT CLOSER than metro waters

when you get thru tantas north passage before you blink you're in 70 and then 100

the deep water ridge moves closer to the shore the further north you are eg deep water off tantas is a lot closer than off coral bay, and off west side of murions it's real close.

can count on one hand in two dozen trips the amount of times we have 'had' to go over the horizon to catch decent fish....doesn't mean we haven't been out REALLY wide on the troll but very safe to say you can hit 500plus without using too much juice....

 i will let you know how we get on 

You can get them in the 200's as well as stated previously the finding the steep ledges with solid soundings on top is the key.

Goodluck 

Has anyone chased them North of Coral Bay?
Looks like a 25nm stint North but the shelf comes right in similar to Exmouth. Is it a worthwhile trip?

 went out with a local not long ago. headed straight out fron tantas in the 270m mark plenty big rubys

 the deep water ridge moves closer to the shore the further north you are eg deep water off tantas is a lot closer than off coral bay, and off west side of murions it's real close.

You can be  north of Coral bay  and south of Yardie Creek and you will find the deep water is closest there, of all----Only a few miles off the stretch South of Winderabandi Point down to Norwegian Bay, which is why the whales really cut the corner there, and why they established a whaling station. I reckon it would only be 15 minutes on a good day to 300 metres + out of the South Lefroy entrance. Only one boat that I know of out of there does it in the period we stay there (June/July), and it's all he does. 

Another Ruby sounder shot if it helps, 587 with a TM260

 couple of ripper shots there lads, just zoom out a little next time so i can see the gps 

 As others have said. Over 200m depth usually. A lot of the time you will find grey band in holes of up to 5-30m and then rubies on the flats either side of the hole. Lots of areas for them out there. Ive caught them out there in 470m north of the lighthouse and fave was 260m 25nm south of tantas.
