Our Roots

Since 2016, Koala Arbor Consulting Arborists have taken pride in looking after people and their trees with support, certification and advice. Founded by David Shrimpton, an AQF Level 5 Arborist with horticultural and climbing arborist qualifications, Koala Arbor brings experience, responsibility and warmth to our many relationships across the Sydney region.

Orchid Walls

At Koala Arbor we have a love of native plants, but especially native epiphytic orchids and ferns. We have several systems using all recycled materials that can allow for these beautiful plants to be installed in vertical spaces. These plants are great where space is limited or where light is restricted from partial shade through to heavy shade. Please feel free to contact us for further information or a site assessment to provide pricing and feasibility options for our different systems.
