Border rebels rallied outside environment minister Sussan Ley's Albury office on Monday calling for more action on climate change.
The Albury Wodonga Extinction Rebellion group said by turning a lemonade stand into a oxygen and fresh water stand is demonstrating what "the future looks like".
Protesters lined up to pay for a cup of drinking water and a second on the oxygen mask.
"This is going to be our reality unless Sussan Ley and her government act on this climate emergency now," co-organiser Eli Davern said.
"At the current rate we are going it is looking like we will start paying for water and oxygen.

"You have seen the last few weeks the incredible smoke haze we have had in Albury and around the country with some of the worst air quality in the world.
"This isn't normal."
Mr Davern said while people generally stereotype climate protesters as "kids not wanting to go to school", the group of Border protesters are "from a wide range of backgrounds and ages".
"People tell me to go back to school but what is the point learning about a world that might not be there very soon," he said.
"Our Albury-Wodonga XR group is growing rapidly and as you can see by the people here they are of differing demographics.
"We just all want more action on climate change and are sick of the government's lies."
While Mr Davern said Ms Ley has "refused" to meet with him the local member said she has made efforts to meet with protesters and met with a student climate group last week.
"As I have indicated previously, we both agree on the need to address climate change, but differ on how to go about that," she said in a statement.
"Our government is committed to meeting its emission targets, and one of the ways we are doing this is by being a world leader in renewable energy."
Ms Ley wasn't at her office on Monday as she was in parliament in Canberra.
Protesters also handed letters to Ms Ley's office.
