G'day Cheryl,

There isn't a separate kettle for this system as they have designed the Jetboil 5L FluxRing Cooking Pot to boil water quickly. This can boil 1L of water in under 3 minutes. 

You could get something like the Sea to Summit X−Pot Kettle 1.3L, I have just tried this in-store and it just squeezes into the Basecamp bag with the stove!

G'day Jordan,

We don't sell this as a replacement part sorry, you could contact STS Brands to see if they can source you one, just fill out their Online Enquiry Form.

G'day Nick,

There isn't a universal regulator option for the Genesis systems.  Whilst we don't sell replacement regulators, but they are available from Jetboil if you lose or misplace them.  

G'day Nick,

Just to clarify with this, Jetboil in Australia actually operate under the banner of Sea to Summit (along with a bunch of other high-end brands), or you can go to Jetboil USA.
Either way, you're dealing with Jetboil - sometimes we may not be able to get certain parts in Australia, in which case the option to get it for you may be there, otherwise you'd get intouch with the US.

Hope that helps, sorry!

G'day Brian,

We've heard back from Jetboil in the US, here's their response:

The adapter hose that is purchased MUST be connected to the regulator. You cannot bypass the regulator. Here is what we tell our customers in the US:

You must connect the stock regulator to the Fuel input Port on the stove as normal. The top-end of the adapter hose will then get secured to the regulator. NOTE: the hose must not have an in-line regulator. The lower end of the hose should be connected directly to the bulk tank threads...again...NO additional regulator.

I highly recommend taking the original Propane Regulator arm that comes with the stove to a reputable propane supply store (they're specialists!) and tell them you need a thread adapter hose for connecting the regulator to a standard 20 lb. Tank valve. They should be able to help in selecting the hose and they might even offer such a hose in different lengths.

When all connections are made and leak-testing has been performed on all connections to confirm there is no fuel leakage, slowly open the tank valve to charge the hose/system. This should only take a moment and then you may proceed to open the tank valve fully. From there, refer to the user manual for normal operation of the stove.

As with all propane connections of this type, the system should be disconnected after use to relieve back pressure on the internal regulator components.

Based on this info, grab one of these hoses for 3/8th BSP bottles, or these for POL/LCC27 cylinders (I've tried it out in person just now), and just be mindful of the considerations, and precautions, as mentioned above.

G'day David,

As far as I'm aware Jetlink isn't a feature, more so a specific hose that allows you to connect multiple Genesis stoves together using the original connection that exists on the stove itself.

The Jetlink hose isn't available in Australia, as I don't believe daisy chaining multiple gas stoves is considered a safe option by the Australian Gas Association.

Alternatively, just get a double adaptor outlet for your gas bottle that allows you to connect two stoves to the same supply.

G'day Adam,

Thanks for this - Tara forward on your message, I've tried to track down your order but havent had any luck sorry.

We have been in contact with Jetboil Australia for clarification. Australian model is not compatible with the USA Jetlink function, its a rework of the international version to pass our Gas Safety Standards, allowing it to be sold here.

There's no need for a janky Amazon adapter solution - as stated in the original answer, you just need a double adapter for your chosen gas bottle.
3/8th BSP are the most common refillable camp bottles due to their size, so you'd just need a Double Adapter and 2 x BOM-3/8th BSP hoses.
If you're using an old POL/LCC27 gas bottle you'd need this Double Adapter and 2 x  BOM-POL hoses

G'day again Adam,

My only other thought would be if you've considered something like a 1.25kg 3/8th BSP refillable LPG bottle?
We swapped to one of those instead of the Propane cannister, more gas for a similar pack size, and found stoves seem to run better off it.
If you're committed to the Propane bottles you don't have much options as you've mentioned.  Just be mindful of doing your leak tests, etc and being as safe as you can with the gas.
