Swap and Go Prices - Swap and Go Gas Bottle PricesAt the time of this writing, typical SWAP'n'GO gas bottle refill prices range from the mid $20s to the low $40s for 8.5kg gas bottles*.

It varies because SWAP'n'GO gas bottle refills are sold by independent dealers who set there own SWAP'n'GO gas bottle prices.

Elgas does not have a SWAP'n'GO Recommended Retail Price - RRP - meaning the SWAP'n'GO gas bottle refill prices are totally under the control of the dealers.

For this reason, it may pay to shop around, as SWAP'n'GO gas prices can vary quite a bit, as previously mentioned.

"Swap and Go Prices" is just another way to say the same thing but SWAP'n'GO® is the registrered trademark.  So, when you search for Swap and Go gas bottle prices you will still get the same information.

BBQ Gas Refill Prices

Gas refill dealers, like the local service station, are also independent. So, BBQ gas refill prices are also set independently by the dealers.

Once again, this makes it wise to shop around.

Gas Bottle & Regulator Questions

Please see Are BBQ Gas Bottles 9kg or 8.5kg?


The full weight of gas bottles can vary based on the weight of the empty bottle. 

The weight of the empty bottle, or tare weight, is stamped on the neck ring of the bottle. 

To calculate the full weight, you add 8.5kg to the empty (tare) weight of the bottle and the total is the full weight. 

Full Weight - Tare Weight = Gas Remaining

Every SWAP’n’GO gas bottle refill is precision filled, on a digital scale, to either 8.5kg (large bottles) or 3.7kg (medium bottles) and leak tested by Elgas technicians.

Look for the yellow seal on the neck of the gas bottle which indicates that it has been quality checked and filled to safe industry standards by Elgas SWAP’n’GO.


A Primus gas bottle is a gas bottle fitted with a Primus valve. 

These are not very common and are not offered as part of the SWAP'n'GO programme.

Refillern got gasDue to the popularity of SWAP'n'GO, staffing issues and safety concerns, all of the major oil marketing companies removed refilling from their company owned sites a few years ago. 

The remaining refillers are independent service station operators and multi-site groups, although some have major oil company branding.

The numbers have now stabilised and no further significant reduction of refiller sites is expected.

Elgas is one of the largest suppliers of LPG to gas bottlr refillers and we support them as well as our SWAP'n'GO network. 

In fact, many of our independent customers have both SWAP'n'GO and Elgas gas bottle refill gas.


Safety Questions

At Elgas, we pride ourselves on our bottle quality.

All SWAP’n’GO gas bottle refills are either new or quality checked and have been refurbished by trained technicians.

  • It is best to store gas bottles outdoors in a well ventilated space.

  • Gas bottles should never be stored indoors.

  • Gas bottles should always be stored upright.

  • Do not store gas bottles near an ignition source.

  • If you store your BBQ or patio heater indoors, when not in use, you should always detach the gas bottle first and store it separately outdoors.

Manually refilled cylinders can be incorrectly filled causing the cylinders to vent gas through the pressure relief valve that is part of the main valve.

This can happen, with an overfilled cylinder, as the gas gets warmer and the pressure builds.

Venting can be a very dangerous situation if it occurs near people or an ignition source and especially in vehicles.

SWAP’n’GO® gas bottle refills are done by weight on very accurate digital scales.

The total gas bottle refill weight is calculated based on the empty weight of the cylinder plus the gas.

The scales are reset for each cylinder to achieve the proper full weight. So, you can rest assured that the gas bottle refill you buy from SWAP'n'GO is safely filled.

SWAP’n’GO also performs two leak checks on each cylinder before it is delivered to your local dealer.

We always check the inspection date on every cylinder we fill and only those with valid dates are filled.

Cylinders with expired dates are inspected internally and externally, have new valves fitted and have a new date stamp applied.

In Australia, this is a very unlikely problem, as the temperature would need to be far below zero.

Extremely cold sub zero conditions can affect your BBQ gas bottle, particularily as it gets low on gas. 

There could be liquid gas within the bottle that will not come out. 

The reason for this is that the liquid gas absorbs heat from the metal walls of the gas bottle to achieve vapourisation, which is the process of going from a liquid to a gaseous state. 

As the volume of liquid gas gets lower, there is less metal surface area providing heat to the gas so it may not 'boil' and vapourise in extremely cold conditions, when the metal gas bottle become very cold.

The best solution for this is to keep the bottle in the sun, on cold days, so it absorbs as much heat as possible. 

Alternatively, switch to a full or near full bottle. 

You can use the lesser filled bottle on another day, when the temperatures are warmer.
