Viva Energy shares slide, ASX trading halt after Geelong refinery fire

A significant fire broke out at Viva Energy Group’s Geelong refinery on the evening of April 15, 2026, affecting the gasoline/alkylation complex. The company reported no injuries and said the incident originated in a key motor-gasoline production unit, prompting an immediate operational response.

Following the blaze, Viva Energy requested a trading halt on the Australian Securities Exchange and notified the market that a detailed impact assessment was underway; the ASX granted the halt pending the company’s announcement. Local safety authorities, including WorkSafe Victoria and Fire Rescue Victoria, attended the site to provide technical support and investigation. Early reports indicate equipment failure as a likely cause.

Initial operational updates show the refinery was operating at minimal rates immediately after the incident, with selective units progressively returning to service. Industry briefings and company statements indicate petrol production was the most affected product stream, while diesel and jet fuel production were less disrupted; Viva Energy has signaled plans to lift output to over 90% of capacity within weeks subject to repairs.

The Geelong refinery is one of only two remaining large-scale refining assets in Australia and plays a material role in domestic fuel supply. Market commentators warn that any prolonged outage would heighten dependence on imports, tighten spot fuel markets and risk short-term price volatility. Federal and state authorities are monitoring the situation to ensure supply continuity.

Analysts say the market impact will hinge on the duration of the outage, repair costs, and insurance outcomes. The ASX trading halt leaves near-term share price discovery on hold until Viva Energy provides further technical and financial updates; investors will closely watch operational recovery timelines and government responses that may affect domestic fuel availability.
