 Comments
 Recent mid-stem failure due to fungal attack.

 The remaining trunk has epicormic growth from its base. There is evidence of a hollow trunk at
 ground level.

 There is multi-stem Brush Box growing with it adjacent Tree 1 with side branches encroaching over
 the neighbouring unit roof.

    • Re-inspect in 12 months.
