Here are common kinds of long‑term investment organisations operating in Australia, plus well‑known examples in each category and a short note on what they do. If you want, I can follow up with performance, fees, product types or recent news for any specific name.

How to choose a long‑term investment company

• Purpose: superannuation, taxable investments, or institutional mandates? Choose accordingly.
• Time horizon & risk profile: some funds target capital preservation and income, others long‑term growth.
• Fees & structure: LIC, managed fund, ETF, or super product — fee structures and tax treatment differ.
• Track record & strategy: look at long‑term performance (5–10+ years), manager tenure and investment philosophy.
• Governance & transparency: size, reserves, liquidity policy, and disclosures matter for long‑term reliability.

If you want, I can:

• Provide a longer list of LICs and their current market tickers.
• Compare a few specific funds/managers on performance, fees, or holdings.
• Explain how to invest through super vs. brokerage vs. LIC for a long‑term strategy.
