mfexpanda at bbq galore they have them but not long enough I think 1500 or 2 meters so they gave me a number of a bloke in spotswood who makes them as long as u want here it is James Shields+co 190 hall st spotswood near the spoty pub 93991077 hope that helps I have a friend at bbq purchasing a Ziegler+ brown or ziggy twin burner with 2 flat plates comes with 2 grill ones trolly and a warming rack don't know how much yet
they don't have 3 meter ones any more at least at hoppers that's what they said or the store at watergardens which is where my work mates wife works I think its there who cares as long as I get a bbq at staff discount giddy up
I have a store on eBay and sell 3m s/s gas hoses. I get them manufactured in Australia specifically for Weber Q's with the stainless steel sheath. I only sell top quality and AGA certified gear. Sold a few hundred (incl. gumtree, trading post and retail) and with 100% feedback to date.
Hoses can't be longer than 3m and even then there's a grey area with compliance to Australian Standards... I won't confuse people with all the details but it also depends on the BBQ being used with the hose ( I.e. The BBQ manufacturer needs to certify the BBQ with a 3m hose).
It's tight competing with Chinese $hit on the market - I sell em for $64.95 on eBay (inc postage). If any Expanda members want one I'll do em for $59.95 to anywhere in Aus via regular post - just PM me.
Don't specifically need a weber brand, most extended hoses work, mine from Jayco dealer.
Just need the correct thread which is fairly standard from what I found when looking around.
