Today, we continue to expand and excel at what we do; expanding to new countries, developing new technologies, and pushing the boundaries of what we can achieve in every market, every day. In 2019, we entered the US market while continuing to broaden our presence across Australia and New Zealand. We have a vision for the future and will continue to shape the industry across the globe.
