I'm not an expert on Australian labour law but I'd be surprised if there were not legal mechanisms similar to protect employees there too so you should assume all Babcock staff will come across and then, as outlined by Apate, the matrix comes out.
Unlike in Europe, there is no equivalent to the Transfer of Undertakings Regulations (or TUPE). If a business is sold or outsourced, employees will only transfer if the ‘new employer’ makes an offer of employment that the employee accepts. Where employees transfer in these circumstances, the new employer may become liable for their accrued leave entitlements. In addition, any enterprise agreement covering the employees is also likely to transfer to the new employer.
