EARTHLY MATTER
Project Description The Wollert Quarry Project is a housing project that involves the staged remediation of the Wollert Quarry whilst also challenging traditional approaches to housing on the urban fringe.
Very often, little regard is given to the landscape in the aftermath of quarrying. Unearthing millennia old blue stone and sandstone, not only disrupts the land itself, it disrupts the those that depend on it. The Earthly Matter studio analysed nuanced methods of extracting and utilising these earthly materials, whilst also paying careful consideration to land on which these materials were extracted. The Wollert Quarry Project focuses on the remediation of the Hanson Clay Quarry in Wollert and proposes a unique solution to not only remediation the quarry using materials from the quarry, but also addressing issues facing communities at the Urban Fringe.
In an aim to increase the biodiversity of the site, the land should be remediated using local native vegetation including: River red gum (eucalyptus), grassy soil plains, stony knoll and treed shrubland and Brackish wetland. These specific types of native vegetation have been selected from a study on the neighbouring land. Over time, the quarry is to be rehabilitated throughout a series of stages, with grassland and vegetation being established first.

RETHINKING REGIONAL RECOVERY
DESIGN STUDIO Tutors: Nikhlia Madabhushi
The catastrophic bushfires experienced during the end of 2019 and throughout the summer illuminated the increasingly devastating impacts of climate change and our requirement to adapt to a changing landscape. Whilst aiming to maximise our skills as architects and facilitate community security in the light of the expected length and frequency of fire seasons; this research-led studio aimed to speculate on how we might harness this collective power in order to forge, fortify and adapt our built environments for a brighter future, with all due respect paid to vernacular peculiarities and local knowledge.
Project Description The Bairnsdale Conservation Centre will provide educational opportunities for farmers, conference spaces open for discussion and collaboration, improved access and awareness for soil support, health safety and soil testing.

Materiality & Construction
The conservation centre serves to test and explore this dilemma but also living that dilemma in and of itself as a construction as well as of a design to educate, encourage and enforce. It’s a living project, and displays examples of effective techniques used to remediate a site post-fire.

SLOW RECOVERY
The Abalone fishery generates $6,000,000 for the local economy annually. However, over the years, fishing and boating has become a contested subject in terms of the ecological impact of commercial fishing and heavy tourism. The consequences of the 2019/2020 bushfires and Covid-19 has led to large job losses due to the drop in Abalone sales. Project Description The Mallacoota Main Wharf Project attempts to acknowledge the tensions between locals and visitors, encouraging spaces for cohesion and stability. The proposal consists of three temporary and permanent architectural propositions that are connected by a walking path along the Mallacoota Coastal walk. The project focuses on educational opportunities for visitors in order to learn about how the town's history has been heavily intertwined with fishing culture, improving social and economic viability as well as improved access along the coast. The outcome of the project serves to enhance employment opportunities for local fishermen, provide them with the appropriate infrastructure they need and integrate sustainable fishing practices in order to respect the lands integrity.

TRADITIONAL FISHING PRACTICES ES
TYPES YPES OF NATIVE FISH SPECIES
HOW? Aboriginal and Torres Strait Islander peoples primarily take dinghies out to fish, and use nets, spears and fishing lines with metal hooks. Diving is also a traditional practice for collecting Abalone.
Dusky Flathead
Yellow-eyed Mullet
WHEN? Seasonal knowledge: The natural signs around them tell which season it is; different flowers in bloom, changes to the colour of leaves, changes in tides and winds. The signs and seasons tell them which fish are big and ready to be taken, as well as changes in the colour and smell of the sea brought by algal blooms tell them when there are yindi maypal (big shellfish).

WHERE? Fishing has traditionally been done on beaches and in shallow pools. Rock pools are also used as natural tidal fish traps to ensure that when the tide goes out, fish are caught in the pools and ready to be speared. Basket traps are placed into creeks for use during king tides and built stone weirs are used for shallow lagoons.

SAILING CLUB EXPANSION
Project Description Harbouring Krambruk attempts to address the underlying issues associated with the current development proposal of the harbour. This included upgrading the existing fishermen’s co-operative building and expanding the sailing club to reflect the towns heritage, with the rest of the propositions contributing as part of the sites urban weaving, encouraging ecological sustainability and connectivity. These interventions have been designed thoughtfully to withstand the sites predicted 100 year storm tide inundation and attempts to make the Apollo bay foreshore a resilient, educational and appealing harbourside for locals and tourists. Through the development of an enhanced and thoughtfully articulated infrastructure development plan, a more coordinated effort for environmental and heritage conservation can be made.
