The post said after the time was up, they were asked to leave the premises immediately although there are still plenty of belongings inside.
Earlier Facebook posts show PhotonFlux signed a lease in December 2016 for the shop.
"The landlord has ever since been interfering with our business and would not allow us to trade to our full potential. They found ways of using the 'system' to disrupt us."
This included things like the landlord objecting to a liquor license renewal in 2018 and refusing fibre internet being installed.
One week ago, the landlord changed the locks and evicted them out of the building.
"They cancelled the lease on us based on breaching the lease for turning his building in a non-complaint building for not filling a change of use. We have been working on this change of use with council for the last six to eight months."
The landlord did not reply to a request for comment.
