Choosing an aged care home11 min readPublished on 27/07/2026

Siblings who disagree about aged care: who actually decides

One says it's time, another calls it abandonment, a third never picks up. Months pass and your parent declines. No sibling has authority over the others, and being next of kin carries no legal power — what counts is an enduring power of attorney or enduring guardianship, and the names differ in every state. Here is who decides, what you are really arguing about, and the free help almost no family uses.

Why this article matters

Built to reduce uncertainty for families who need to understand costs, urgency, waiting lists and real options.

The deadlock that costs the most

One says things cannot go on like this. Another replies that in a home "they just park you in front of a television". The third lives interstate, knows the least and has the firmest opinion of anyone. Meanwhile the person you are all talking about is getting worse.

It is probably the most common situation families face and the most underestimated: a disagreement between siblings does not delay the decision, it replaces it. While the argument runs, no assessment is booked, no home is toured, no application goes in. And when the crisis arrives — a fall, a hospital admission, a carer who stops — you take the only option left, which is almost always the worst one.

Who decides, legally

  • Your parent decides, for as long as they have decision-making capacity. Capacity is presumed and it is specific to the decision — someone may be unable to manage their banking and perfectly able to say where they want to live. An adult with capacity is not moved into aged care because their children agree it would be sensible. Their view is not one factor among several: it is the decision.
  • No sibling has authority over the others. Being the eldest does not count. Paying the most does not count. Being the one doing the daily care does not count either. There is no hierarchy among adult children, which is precisely why these deadlocks last.
  • Being "next of kin" gives you no legal power. What carries authority is an enduring power of attorney for financial matters and an enduring guardianship or medical treatment decision maker appointment for health and lifestyle decisions. These are separate documents, and — importantly — they are named and regulated differently in every state and territory. A document made in one state does not always operate the same way in another, which matters a great deal in families spread around the country.

If nothing was ever signed and capacity has gone, authority has to come from the state civil and administrative tribunal — NCAT, VCAT, QCAT and their equivalents — through a guardianship or administration order. That is slower, public, and frequently the thing that turns a family disagreement into a permanent rupture.

So the first practical job is dull and almost always skipped: find out what documents exist, which state they were made in, and where the originals are. Many parents signed them years ago and never mentioned it. If nothing exists and your parent still has capacity, that appointment matters more this week than touring homes does.

What you are really arguing about

  • The load is not shared. Whoever provides the daily care is exhausted and wants a solution. Whoever lives further away does not see the exhaustion — they only see the proposal, and they judge it.
  • Money has not been put on the table. The basic daily fee, a possible means-tested care fee, and the accommodation payment — a lump sum, a daily payment, or a combination. Then the question nobody says out loud: whether the family home is sold to fund it, and what that means for an inheritance. Someone who fears they cannot contribute often objects "on principle", because that is easier than saying so.
  • Guilt is looking for someone to blame. "We're abandoning her" is rarely a judgement about the other person: it is the fear of the person saying it, turned outward. The sibling who objects most fiercely is often the one who has done the least hands-on care — not hypocrisy, just how guilt works.

The method that breaks it: from principles to facts

  • An ACAT assessment. Arranged through My Aged Care, it is free, and it is the gateway to everything — residential care, respite and home support alike. It produces an independent, written statement of what your parent can and cannot manage, and it ends the "well I think she's still fine" exchange. Most importantly: being assessed commits you to nothing and forces nobody into a home. It is simply the only thing that starts the clock running for you instead of against you.
  • The real cost of both routes. Staying home with the support genuinely required — including what a home care package would and would not cover, and how long the wait for one actually is — against residential care after a means assessment through Services Australia. These are numbers, and they usually surprise both camps.
  • Three specific homes, with names, fees, and what their most recent quality assessment found. This is the step that changes everything: while "a nursing home" stays an abstraction, everyone projects their own fear onto it. In front of three real places, you are discussing something checkable.

The free help almost nobody uses

The Older Persons Advocacy Network, on 1800 700 600, provides free and independent advocacy. Families think of it only once something has gone wrong in a home — but advocates also help at exactly this stage, when a family cannot agree and someone needs to make sure the older person's own voice is not lost between their children. A single call often changes the tone of the whole discussion, because the advocate's job is to represent your parent, not to take a side between you.

The conversation worth having

Have one, with a rule stated at the start: we are talking about what Mum or Dad needs, not about who has done more over the last ten years. Four points, in order:

  • What the assessment says — read it out, do not debate it.
  • What your parent wants, if they can say. Ask them directly; do not have it relayed.
  • What each of you can put in: money, time, presence. In dollars and in days, not in good intentions.
  • Who does what, by when: who books the assessment, who gathers the financial paperwork, who tours homes. With a date.

If someone does not turn up, carry on and tell them in writing what was decided. People who opt out of decisions do not get to block them.

When you need a third party

  • the GP, who can say with authority that living at home is no longer safe;
  • an advocate through OPAN, as above;
  • elder mediation, available through community justice and dispute resolution services in most states, where the conflict is old and aged care is only the latest chapter;
  • a solicitor for the enduring documents — done properly now, they prevent a tribunal application later.

If the deadlock holds and there is real risk

There is a point past which waiting is not neutral: repeated falls, medications not taken, someone left alone for hours, a carer close to collapse. There is also a harder possibility worth naming, because these disputes sometimes conceal it — where one person is controlling the money or isolating the parent, that is elder abuse, and the national helpline 1800 ELDERHelp (1800 353 374) exists precisely for families who are not sure what they are looking at.

The reverse applies too. If you are the one providing care and cannot continue, saying so explicitly and with a date — "from September I can no longer do the afternoons" — is more effective than any argument about principles. It makes visible a load that stayed invisible precisely because it was working.

The practical point

You do not get out of these deadlocks by convincing anyone. You get out by putting facts on the table nobody can dispute. An assessment, an honest set of numbers and three real homes will close in an afternoon a discussion that has been stuck for months.

If what you are missing is the concrete options, Curalune Care Help puts them in your hands: 3–5 homes that match the real situation within 24 working hours, with contact details, links and a ready-to-send message you can put to all of them at once — something checkable to bring to the next conversation with your siblings.

Enduring powers of attorney, enduring guardianship and medical treatment decision-maker appointments are governed by state and territory law, under different names and with different requirements, and aged care fees and assessment arrangements are periodically reformed. Check the position in your parent's state and confirm fee details with Services Australia.
