Just signed up for 100/50 2tb for $70 a month for first six months. Not a bad offer for ex MUNGI customers. See https://www.ozbargain.com.au/node/417748
"We're aware of the unfortunate news this afternoon about Mungi entering voluntary administration and ceasing operations, and we're aware that many Mungi customers need assistance setting up new services with an emphasis on speed of transition to prevent downtime.
DCSI is offering Mungi customers $10 per month off any plan over $60 a month for their first six months with us, along with our usual free activation (BYO router). If you apply online, comment MUNGI in the notes in your application. Phone applications can be made on 1300 66 55 75 – let the team member know you're transitioning from Mungi.
