Case Name & Citation: Deputy Commissioner of Taxation v Saliba [2020] NSWSC 1655
Operational Mechanics: Parents register an adult child as a nominal director and shareholder of a family operating company or corporate trustee. Trust distributions and corporate profits are allocated to the child on paper ('tax streaming') to exploit their lower marginal tax bracket.
The Siphoning Mechanism: The actual cash distributions are retained entirely by the parents or diverted into accounts the child cannot access. Unserviced corporate tax liabilities, Superannuation Guarantee Charges, or unpaid Division 7A loans accumulate within the entity.
The Trapping Mechanism: The Australian Taxation Office (ATO) issues Director Penalty Notices (DPNs) and personal income tax assessments directly to the adult child under Division 269 of Schedule 1 to the Taxation Administration Act 1953 (Cth). The child becomes personally and legally liable for catastrophic tax debts, destroying their credit rating, bankability, and career, while the parents hold the physical assets.

Case Name & Citation: Calverley v Green (1984) 155 CLR 242
Operational Mechanics: Parents instruct an adult working child to voluntary salary sacrifice into superannuation over multiple financial years to maximize funds under the First Home Super Saver (FHSS) scheme.
The Siphoning Mechanism: Upon releasing the superannuation capital for a home purchase deposit, the parents force the child to buy a property registered either under the parents' names or as tenants-in-common where the parents hold the majority share. Alternatively, the child is forced to execute an unrecorded side agreement declaring the property is held in trust for the family enterprise.
The Trapping Mechanism: The child’s retirement savings are permanently liquidated and converted into real estate equity controlled by the parents. The child remains legally encumbered with mortgage debt while stripped of both liquidity and genuine homeownership rights.

Case Name & Citation: Fair Work Ombudsman v Yenida Pty Ltd [2018] FCCA 1342
Operational Mechanics: Upon entering the workforce, the adult child is instructed to configure their employer's payroll software to deposit 100% of their salary into a joint bank account managed exclusively by the domestic patriarch.
The Siphoning Mechanism: The parents control all banking credentials, cards, and digital wallets. The adult child is issued a small, discretionary weekly 'allowance' for basic living expenses, subject to behavioural compliance.
The Trapping Mechanism: The child is deprived of the ability to accumulate independent savings or establish personal credit history. Attempts to alter payroll banking details are met with emotional extortion, physical threats, or accusations of abandoning the family.

Case Name & Citation: Commercial Bank of Australia Ltd v Amadio (1983) 151 CLR 447
Operational Mechanics: Parents leverage an adult child's high professional income (e.g., in medicine, law, or engineering) to qualify for substantial bank loans or refinancing packages for parental investment properties.
The Siphoning Mechanism: The child is placed on the loan agreement as a joint borrower or guarantor. The loan proceeds are deployed into assets owned solely by the parents or siblings, while the servicing obligations fall entirely on the working child.
The Trapping Mechanism: The adult child’s serviceability capacity with financial institutions is completely exhausted. They are legally blocked from securing loans for their own life goals, remaining tethered to the parents' debt portfolio for decades.

Case Name & Citation: Sultan & Sultan [2021] FamCAFC 122
Operational Mechanics: The working child is forced to transfer a fixed, substantial percentage of their post-tax earnings overseas to finance extended family property developments, business ventures, or relative living expenses.
The Siphoning Mechanism: Payments are enforced through systematic psychological coercion, weaponised ancestral duty, and threats of reputational destruction within the local and overseas community.
The Trapping Mechanism: The child's disposable income is driven down to subsistence levels inside Australia. This renders them financially incapable of moving out of the family home or funding independent legal advice.

Case Name & Citation: Kavussanos v St George Bank Ltd [2012] VSC 222
Operational Mechanics: The adult child is instructed to open primary credit card accounts with high borrowing limits, based on their personal income, and issue secondary cards to the parents.
The Siphoning Mechanism: The parents use the secondary cards to fund luxury personal lifestyle expenses, commercial purchases, or gambling debts. The primary liability remains legally attached to the child.
The Trapping Mechanism: The child is forced to allocate their monthly salary to service high-interest consumer debt created by others. If payments default, the child faces personal commercial blacklisting and legal enforcement from lenders.

Case Name & Citation: Lau v Lau [2011] VSC 319
Operational Mechanics: Parents force an adult child to liquidate personal share portfolios, term deposits, or compensation payouts under the guise of an urgent, short-term 'family loan.'
The Siphoning Mechanism: The capital is absorbed into parental accounts or family businesses with no formal loan agreement, interest rate, or repayment schedule.
The Trapping Mechanism: When repayment is requested, the parents deploy emotional manipulation, asserting that 'children do not lend money to parents; everything we built belongs to the collective, and you will inherit it when we pass away.'

Case Name & Citation: Garg & Garg [2020] FamCA 83
Operational Mechanics: As a condition of parental consent for marriage or to satisfy communal expectations, an adult child is coerced into taking out personal bank loans to fund lavish wedding events, gifts, or asset transfers to in-laws.
The Siphoning Mechanism: The financial liabilities are placed entirely on the young adult child, while the social prestige and gift assets are collected and managed by the parental hierarchy.
The Trapping Mechanism: The young adult enters their married life burdened with severe personal debt, severely crippling the financial security of the newly formed domestic unit from day one.

Case Name & Citation: Bosanac v Commissioner of Taxation [2022] HCA 34
Operational Mechanics: Parents purchase real estate, vehicles, or commercial licences in the adult child’s name to evade land tax thresholds, capital gains obligations, or creditor claims against the parents.
The Siphoning Mechanism: The child bears all legal obligations, land tax liabilities, municipal rates, and statutory responsibilities associated with the asset, but receives zero income, access, or decision-making authority over it.
The Trapping Mechanism: The child is exposed to legal enforcement, statutory fines, and tax audits for assets from which they derive no benefit, while simultaneously losing access to first-home buyer concessions.

Case Name & Citation: R v Kannan [2021] VSC 303
Operational Mechanics: Parents require an adult child residing in the family home to pay 'board' or 'rent' at rates significantly above commercial market value.
The Siphoning Mechanism: The parents enforce cash-only payments, preventing any verifiable record of tenancy or board payments while systematically draining the child's paycheck every cycle.
The Trapping Mechanism: By keeping the child's liquid bank account near zero, the parents ensure the child never accumulates the bond, upfront rent, or savings required to secure independent housing, effectively locking them into physical and domestic captivity.
