Step | Action

1 Clear entire offset site. Mulch, strip and stockpile all top layers and weed material.

2 Install main infrastructure e.g. haul/access roads, irrigation water line from treatment plant, water tanks.

3 Install exclusion fencing around weed area.

4 Provide weed treatment to entire receiver site after clearing, i.e. spray all weeds as they germinate for four
weeks prior to seed soil being moved to site.

5 Site soil from Lot 6 transported and installed into the southern part of the rehabilitation site (0.8ha).

6 Treatment to T1 (e.g. coir logs) and soil (0.3ha).

7 Plant she-oak tubes and other trees. Planting included in T1 and T2 areas and incorporates both Stage 1 and
Stage 2 planting targets.

8 Planting of grass trees into T2 area by Council.

9 Install monitoring points.

Practical completion for On-Maintenance Stage 1 has been achieved as follows:

* areas approximate.

In addition to the above, the T1 area has been rehabilitated. This rehabilitation has been brought forward (i.e.
exchanged for part T2) with some 3000m? treated for weeds and approximately 1500m? (open dune) stabilised with
the use of coir logs, natural vegetation material and the planting of 350 plants (as tube stock) from nine species. It is
relevant to note:

e The she-oak planting has exceeded (by >200) the requirement for the project (i.e. stage 1 and stage 2 offset
ratio target).

© The 350 native species incorporated into the T1 area is above any requirements for Stage 1 or Stage 2
planting.

2.1.2 Additional Works and Fencing

The project has successfully achieved the required planting target for both Stage 1 and Stage 2. Additional planting of
600 trees is proposed (refer Section 4.4).

Parts of the rehabilitation area for Stage 2 will be capped in accordance with the design and specification provided by
Noosa Shire Council (refer APPENDIX B1) — refer Section 4.3.

The Madeira vine area was fenced (exclusion fencing) for future treatment”? and will remain fenced until the area is
deemed secure by the contractors (e.g. buried beneath the GCL liner) which is to be vegetated as per this EMP.

Responsibility for existing fencing on the rehab site will transfer to Blue Care/Lendlease from 1 June 2023 and will be
removed as soon as planting is complete, and all works machinery have demobilised offsite.

10 |t is noted that Council have mulched the weed stockpiles in this area in September 2022. Left untreated this area remains a
weed source and risk for the successful rehabilitation of the balance land.
