Our Team

  • David Cosca

    Managing Director

    In the midst of the 1990’s recession, a young and ambitious David Cosca was presented with an electrical contracting opportunity and decided to grab it with both hands. It was a huge stretch, but he backed himself and delivered. And so Vast Electrical was born.

    That innovative, problem-solving approach and ‘can-do’ attitude is ingrained in our DNA. For over 20 years we’ve backed ourselves to take on new challenges and get the job done on time, on spec and on budget. We want to set the benchmark that others aspire to achieve. We consider each project a partnership, and we step up to deliver outstanding results underpinned by safety, training and technology. We’ve never paid LDs yet, and we don’t plan on starting now.

    David thinks big, and has built a team that has the skills, experience and drive to take on new challenges and reliably deliver the high quality results we’re known for. Growing from a small team to a big deal requires a strong culture, and David’s role has changed significantly over the journey – while he still gets onsite where he can, he now oversees all projects and focuses on mentoring our team to be their best.

    David is excited to watch our young and hungry team continue to develop the skills and experience to reach their full potential and deliver great results for our partners. Our success has been driven by our people, and it’s our people that will drive our standards of quality and reliability over the next 20 years and beyond. Who knows what we can achieve?

  • Sandra Cosca

    Executive Director

    Vast Electrical’s record of quality and reliability is driven by our people and our culture. To maintain our high standards, Sandra’s primary focus is to support our people and strengthen our culture. It starts with having the right people who align with the company’s values and who share the same hunger to be better every day. We then ensure our people have the tools, training and safety measures in place to get the job done safely on time, on spec and on budget. Finally, everyone from the Managing Director down needs to continually reinforce a culture of safety, quality and delivery through our actions.

    Sandra works with the Managing Director, CFO and Executive Leadership team to set and refine the strategic focus of the business to ensure our activities are aligned to our financial focus and company values. With a strategic outlook underpinned by an innovation mindset, we harness technology to streamline project reporting and completion and provide exceptional solutions for our partners.

    What excites Sandra most about her role is helping our people to grow and be their best. Vast Electrical’s goal is to set the standard in electrical contracting that others aspire to reach. Sandra is proud of what we’ve achieved to date, humbled by the team we have assembled, and excited by what the future holds.

  • Ryan Campbell

    Project Manager

    Ryan’s focus is to make life easy for our builder partners. Our core value of ‘reliability’ is characterised by doing what we say we will – so builders don’t need to manage us or deal with errors.

    Because we run lean construction projects to minimise costs and complexity, Vast Electrical project managers are intimately involved in every aspect of the project. We work closely with the site foremen to ensure we continually meet the builder’s requirements while managing costs and meeting deadlines. This provides total transparency for builders.

    Our commitment to creating new leaders from within means there are opportunities for great performers to progress their careers. Having joined Vast Electrical as a fourth year apprentice, Ryan is grateful for the opportunities and mentoring he’s received, especially from Managing Director David Cosca who instilled in him an absolute focus on high quality and efficiency.

    Ryan has worked on a range of exciting and challenging projects including the redevelopments of Ikon Park, Malt District and Caulfield Racecourse. He brings out the best in his team by setting high standards, recognising great work and reinforcing the skills, values and attributes they need to succeed with a focus on quality, reliability and teamwork.

    In this industry you need to keep adapting to keep ahead, and Ryan looks forward to continually improving project delivery and providing great outcomes for partners.

  • Darren Wade

    Project Manager

    Darren’s focus is helping builders deliver successful projects and helping end clients bring their project vision to life. He finds it rewarding to contribute to a project from start to finish that offers many benefits for clients and the broader community.

    A big part of Darren’s role is supporting the onsite team so they can concentrate on getting the job done on time and on spec. He is energised by the sense of onsite camaraderie and purpose where everyone is working together to achieve one goal, like a successful sports team. This sums up our culture: we want to build a great team environment where everyone works together to get the best result.

    Equality and family are central to who Darren is as a leader and a person. This alignment of personal and company values explains why he has fitted in seamlessly to the Vast Electrical family.

    Looking ahead, Darren’s focus is ‘longevity’: both by delivering successful projects for the next 20 years, and by contributing to a team who reaffirms Vast’s reputation for quality and reliability on every project.

  • Natasha Sekuloski

    Project Support

    As a highly organised and detail-oriented person, the Project Assistant role compliments Natasha’s skills. She supports each project team to ensure there are no onsite delays to projects, freeing up the directors and project managers so they can get on with the job.

    Natasha is involved in all aspects of project delivery, from tenders through to completion. Her varied tasks ensure no two days are the same; every project throws up new challenges and provides opportunities for us to do things better.

    Being an important and reliable part of a team that delivers outstanding results for partners provides Natasha with great satisfaction. There’s a real sense of achievement as we deliver each successful project. Working closely with David, Sandra and the project managers has enabled Natasha to grow professionally and personally.

    Vast Electrical is a positive and dynamic place to work, with a supportive culture that feels more like a family. A company-wide focus on continual improvement means the leaders give the team every opportunity to grow and develop. Natasha’s goal is to support others to be their best, particularly through our apprenticeship development activities.
