The pressure is on Vocus Group to bring home its third takeover offer in as many years and allay fears that two previous due diligence exercises by potential bidders had unearthed deep-seated problems with Australia’s fourth-ranked telecoms company.

An industry source said Vocus was confident it could make the latest deal from Macquarie Infrastructure and Real Assets Management (MIRA) work because its health is robust compared with 2019, when separate bids from AGL Energy and private equity firm EQT died early during due diligence.
