A former hospitality worker has won a substantial payout from burger chain Grill'd after allegations she was sacked for speaking out against a low-paying wage agreement.

Kahlani Pyrah, 20, gained national attention this year for taking on her employers at a Grill'd Melbourne outlet. She launched legal action alleging she was fired for seeking to have the company's WorkChoices-era pay deal scrapped and replaced with full award entitlements.

Ms Pyrah was due to appear in the Federal Court this week to make her unfair dismissal case, but the trial was called off after the parties reached a confidential settlement.

The young worker said she was pleased with the outcome and what she had achieved.

"I wanted to overturn Grill'd below-award wages and I succeeded ... that means thousands of Grill'd workers will get a pay rise.""I was able to set a positive example to hospitality workers that you can stand up for better wages and fair treatment and win," she said.
