Our Leadership Team

Gabriel Dio

Managing Director
BE(Hons), MIEAust, CPEng, RPEQ

Gabe is passionate about advancing Australian manufacturing and improving our country’s commercial competitiveness. Since taking over Master Steel in 2018, they’ve realised annual revenue growth, grown the team, entered new markets and achieved Main Roads (TMR) accreditation to MRTS78.

His background in the resources and manufacturing sector spans more than a decade and numerous countries in South East Asia, the Middle East and East Coast of Australia. When combined with his love of innovation, Gabe is providing the leadership Master Steel needs so it can play a role in a brighter future for advanced manufacturing in Australia.

When he’s not planning the next phase of growth for Master Steel, Gabe enjoys staying connected with his Filipino community - whilst eating Mexican food. And if he’s not watching sports, he’s either out playing golf or taking care of his mental wellbeing with some meditation (which also helps when he’s had a bad day out on the golf course).

Bianca Acidera Dio

Commercial Director

Unlike many from her generation, Bianca isn't interested in the vogue industries of today - IT, banking, fashion. Her passion lies in the sectors that others think of as too hard, too dirty or too boring to take on - heavy industry, manufacturing and the like. She’s a highly adaptable person, prepared to roll up her sleeves and loves being in a busy, fast paced environment.

Bianca started out with a background in architecture, design and behavioural studies. She worked in a number of businesses owned and run by her family, focused on retail, distribution and warehousing. Over time, her focus moved to logistics, accounts and operations, where she found her groove - helping operationalise systems, improve connectivity in front end teams and streamline back office functions e.g. point-of-sale (POS) and warehouse management (WMS) systems.

At Master Steel she is playing her part in taking over the reins from a previous generation of steel workers, ensuring a financially successful future for the company. When not giving her favourite calculator a workout, Bianca favours relaxing at home - be it a good binge watching session, cooking up a storm in the kitchen and keeping in touch with family.

David Walsh

Operations Manager
Welding Supervisor (AS1796 Cert 10 & AS2214)

Dave isn’t your typical boilermaker. He’s experienced in highly technical steel fabrication and is licenced to perform high risk work. His 35 years experience spans civil, marine, mining, defence and commercial industries - not just in hands-on fabrication and welding, but in the training, supervision and management of teams.

Dave has extensive experience working with Tier 1 companies and government agencies - both on and off the tools. This includes the Department of Transport and Main Roads (TMR) and Queensland Rail (QR).

In addition to his technical and supervisory background, Dave’s experience extends to operations and business management, incorporating accountability for commercial outcomes, WHS compliance and staff performance.
