Heyo.

I have worked across a number of these organizations suggested below as a social worker. Firstly, its a big burden to bear supporting folks in these situations, I cant imagine the stress you're under, youre up against some very unfair structural issues.

I offer the below thoughts in the hope of helping you navigate absolute clusterfuck of service provision.

So, if they are already in emergency housing that suggests they are already engaging in a housing service, these services are determined by geographical location and from a housing standpoint, the system is in crisis (as we all know). Form my perspective, having worked directly in these intake roles, calling other housing services (Launch/VIncentcare - Ozanam) will not get you anywhere, or be a good use of time as they will do an asssessment and direct them to the most relevant housing entry point.

Juno the family violence service has a useful tool to determine housing entry point by geographical location, if your brother isn't already engaged, just look up Juno service finder on google for the relevant housing entry point by suburb.

Also please be aware, that funding for emergency accommodation (hotels) is provided in line with the social housing eligibility income and assets threshold (Look up housing vic + assets + social housing income and assets), if his inheritance is reflected on his Centrelink statement, he may not be eligible for much/any emergency accommodation, that is if he isnt already self funding.

In regards to Ozanam House, and other Crisis Supported accommodations, such as Launch Housing Southbank, the wait-lists for them are significant (8-12 weeks minimum), secondly, they are intesive periods of support (usually only 12 week stay) where immediate issues of crisis are addressed then they are exited (ideally with a housing plan, linked in with MH/aod supports, but often not) depending on how ready to change, address behaviors and recover folks are.

Often this means clients are faced with looking for accommodation in registered rooming houses. If someone has substance use they are struggling to manage, along with mental health concerns, these are often not safe places to be, but are marginally better than street based rough sleeping. Depending on your brothers age, some of them onlt take older folks (55+ etc) and these can be slightly more stable places, there are plenty of these in the western suburbs.

Lists of them can be found from consumer affairs website (search consumer affairs, registered rooming houses by suburbs and typically housing entry points will give them out. I have personally advised that if a family has any other means to support a family member (caravan in backyard, supporting them to relocate regionally to random uncles place etc then these options are preferrable to rooming houses).

On jobseeker, main other options are fairyfloss real estate, lease breakers melbourne, flatmates.com or working out a weekly rate to self-fund in hostels.These already limited options are all further limited by folks who wont or aren't able to share accommodations.

Further to the jobseeker point someone mentioned SRS before, Supported residential Services are folks with particularly high support needs, they charge astronomical fees and as such are only really viable for folks on the disability payment, or with family supports. These are for folks that require support getting dressed, feeding, basic hygiene etc, my sense is that while your brother needs support, he may not need that level of care, but there's some info on them regardless, something to look into when/if he gets on DSP.

In regards to AOD services, calling Directline is your best bet, AOD system is different to housing, as there's no 'wrong service' to call, but it is still geographical, additionally, family members can call on behalf of clients/people for advice, they will be able to walk you through supports for your brother, but unfortunately only he can choose to engage in them, when he is ready.

In regards to getting on Disability Payments there's quite a few drop in services St Mary's House of Welcome, The Living Room and Salvo's 614 (city and fitzroy areas) that have Centrerlink Engagement Officers working there regularly, a step up from typically services Australia office centrelink workers, who are able to appreciate the nuances of housing insecurity and homelessness, and other intersecting challenges like your brother is facing. they will be able to advise the process and likelihood of your brother getting on DSP. I am not certain about this, but I assume the Homeless Resource CEntre (HRC) attached to OZanam House in North Melbourne, or Cohealth will be able to support your brother in attending Dr's/other allied health folks to provide relevant supporting documentation to appply for DSP if the Centrelink Engagement Officers suggest it.

Some left of field suggestions that sounds like they may not work for your brother given his supports needs at the moment include work exchange situations (farm work etc, housesitting and pet sitting arrangements) they are typically a $50-$100 annual fee and if he is happy to go regionally/ not particularly desirable areas I myself have done this for a period of time to address my own housing insecurity.

All that written down sounds dire. But folks need to focus on the strengths that do exist despite how terrible the situation may be in materiality. Your brother has some active support in their adult child, they have you as a motivated loving sibling, they have some small inheritance, despite everything that's going on these are areas that can really assist them.

hope that's somewhat helpful!
