The short answer is: from $300 to over $1000 per metre
The long answer is: What are the factors that affect the cost?
A few basic rules
If you can easily dig up or access the pipe than do that.
Where tree roots are involved don't just line the affected joint. Line the section as the rootes will grow down to the next joint and re-enter the pipe
The higher the risk of failure the higher the price.
If there is a failure what is the cost to fix the pipe? Who's paying to fix the failure?.
