Drouin at present is undergoing a street-tree pruning program. The trees that grow under powerlines are being 'reduced in height'
for safety reasons – understandably. There is some debate in the community
however, about how excessive or how sensitive the pruning has been in some
cases.
While developers of new estates in Victoria are required to
put new infrastructure underground, most older or longer established
residential areas are still supplied electricity by, in some cases, an ageing
overhead power line system.

Same species, same age, different side of the street |
In 1997, a report to the Parliament of Australia suggested
that to put all existing overhead power lines in the country underground would
conservatively cost $50 billion! It's just not going to happen in 2017, despite
advances in directional drilling techniques, etc.
The above report also highlighted the improved property
values that are achieved when overhead power lines are replaced with
underground cables.
Energex, the South-east Queensland electricity distributor,
has produced an interesting cost/benefit analysis of putting cables underground
versus overhead on poles – can you guess which side of the argument they come
down on – "Most of our high voltage transmission lines are built overhead
due to costs, ease of repairs and environmental considerations".
The debate continues.
