  • With the deployment of the nbn™, Australia now needs additional skilled workers to construct the different network architectures.
  • New network architectures and technologies require the development of new skills and knowledge to ensure success.


  • Working as an nbnTM Approved Training Provider, PERPETUAL LEARNING INSTITUTE has enhanced our traditional courses to align directly to the skills needed for the nbn™ rollout.
  • The development of carefully constructed skill based programs is where we excel – the art of training.
  • Unlike other training organisations which focus primarily on technology, PERPETUAL LEARNING INSTITUTE is structured toward Field Operations staff. Technology theory is combined with large quantities of practical exercises to reinforce the learning process.
  • PERPETUAL LEARNING INSTITUTE is the market leader with regards to hands on practical training that is supported by our real world learning simulators – “We bring the field environment to you”.
