And Russell says the fibre business is just getting started on fulfilling its full potential. "Vocus has great assets and great market opportunity but there are ongoing improvements that we will have to deliver on, we are not the finished article yet," he said. "Our market share is still low relative to (the size of) our network, we have had a good couple of years but we have share to gain. " Telecommunications infrastructure has become increasingly attractive to investors looking for steady returns. 5G might be the talk of the town but the technology relies on fibre for backhaul, which makes networks like Vocus' even more attractive. Aware Super, which has teamed up with Macquarie in carrying out due diligence on Vocus, recently lost out to junior telco Uniti in the race to buy fibre broadband operator OptiComm and is clearly keen on adding fibre to its portfolio. Meanwhile, Macquarie already owns wireless tower operator Axicom and data services company Air Trunk, making Vocus's fibre the perfect fit.
