It was another busy week for Australia's top brokers. This has led to the release of a number of broker notes.

Three broker buy ratings that you might want to know more about are summarised below. Here's why brokers think these ASX shares are in the buy zone:

Elders Ltd (ASX: ELD)

According to a note out of Bell Potter, its analysts have retained their buy rating and $9.10 price target on this agribusiness company's shares. Bell Potter points out that Elders' shares have underperformed materially since the announcement of its proposed acquisition of Delta Agribusiness. The broker thinks this has created a very attractive buying opportunity for investors. Especially as it believes that existing initiatives and its favourable leverage to cattle prices will underpin double digit earnings per share growth through to FY 2027. Bell Potter also makes the point that the Delta Agribusiness acquisition could accelerate this growth profile if it is approved by regulators. The Elders share price ended the week at $6.12.

IDP Education Ltd (ASX: IEL)

A note out of Macquarie reveals that its analysts have retained their outperform rating on this language testing and student placement company's shares with a reduced price target of $6.40. Macquarie remains positive on IDP Education following a very disappointing market update last week. It notes that the company's update revealed a significant drop in volumes because of tough trading conditions in the international student market. Macquarie highlights that IDP Education's EBIT guidance for FY 2025 is approximately 30% lower than both its estimates and consensus forecasts. As a result, its analysts have taken an axe to their estimates for FY 2025. They have also done the same for FY 2026 and FY 2027. But due to a heavy decline from IDP Education's shares, it believes that they are attractively priced at current levels and is urging investors to pick them up while they are down. Particularly given that it sees potential for IDP Education to return to double-digit growth in the near future. This is thanks to cost reduction opportunities and easier comparables. The IDP Education share price was fetching $3.59 at the end of last week.

Lynas Rare Earths Ltd (ASX: LYC)

Analysts at Morgan Stanley have retained their overweight rating and $10.00 price target on this rare earths producer's shares. According to the note, the broker has become even more positive on the company. This is due to Lynas' potential to increase production thanks to the new Kalgoorlie facility. This is particularly important given its position as one of only two global rare earth supply producers outside of China. The Lynas share price ended the week at $9.15.
